fix(tui): close busy-flag race that stuck queue-mode back-to-back sends

Under display.busy_input_mode: queue, sending two messages back-to-back
hung the session on 'Analyzing…' until a manual Ctrl+C.

The submit path only marked the session busy inside the .then of an
async input.detect_drop RPC. dispatchSubmission routes queue-vs-send on
getUiState().busy, so a second Enter inside that RPC window read
busy===false and raced a second prompt.submit down the send path
instead of enqueuing locally. The gateway accepts the mid-turn submit
as a success ({status:'queued'}, not an error), and the client's only
re-queue recovery is gated on catching a 'session busy' error — which
never fires — so the message became invisible to the client-side drain
effect and the UI stayed busy forever.

Extract the ready-prompt submit into a pure submissionCore module and
mark the session busy synchronously at the choke point, before the
detect_drop round-trip, closing the gap for every caller (mainline
submit, queue-edit picks, drain, interpolation). Verified the real
gateway already queues+drains both turns correctly, so the fix is
purely client-side. Adds submissionCore.test.ts whose regression
assertions fail without the synchronous busy and pass with it.

-# Fixable lint issues (import sorting, unused imports, curly braces, etc.) are

-# check in typecheck.yml fails only when un-fixable errors remain.

-# NOTE: AUTOFIX_BOT_PAT pushes DO trigger further workflow runs (unlike

-# run cancels the in-flight one, and since the second run finds no new fixes
-# (the first run already applied them), it exits with an empty patch.
-#
-# ── Security model: two-job split ───────────────────────────────────────────
-#
-# The eslint process executes repo code (eslint.config.mjs, package.json
-# scripts, installed plugins). To prevent a malicious PR from getting arbitrary
-# code execution on a runner with push access, the work is split:
-#
-#   1. generate-patch (unprivileged, contents: read only)
-#      Checks out, installs deps, runs eslint --fix, produces a .patch artifact.
-#      Worst case: malicious code runs here on an ephemeral runner with zero
-#      push permissions.
-#
-#   2. apply-patch (privileged, contents: write + pull-requests: write)
-#      Checks out, downloads the patch artifact, applies it, pushes to the
-#      bot/js-autofix branch, creates/updates a PR, and enables auto-merge.
-#      This job never runs npm, never installs anything, never executes any
-#      repo code. The only input it trusts is the patch artifact.
-#      Skipped entirely when generate-patch reports no fixes (has-fixes != true).
-#      The PR auto-merges (squash) once CI passes. If CI fails or main moves,
-#      the PR is auto-closed and the branch deleted — the next run re-applies
-#      on the current state.

 ### Electron Desktop Chat App (`apps/desktop/`)
 
-A **separate** chat surface from both the classic CLI and the dashboard's embedded TUI. It is an Electron + React + nanostore renderer (`@assistant-ui/react`) that talks to a `tui_gateway` backend over JSON-RPC (`requestGateway(method, params)`). The WebSocket/JSON-RPC transport lives in the framework-agnostic `apps/shared` package (`@hermes/shared` — `JsonRpcGatewayClient` + WS URL helpers), which the web dashboard (`web/`) also consumes; **desktop has no build/runtime dependency on the dashboard frontend** — it spawns a headless `hermes serve` backend server (the same gateway `dashboard` serves, minus the browser UI entirely: `serve` sets `headless_backend=True`, so `cmd_dashboard` skips `_build_web_ui` AND exports `HERMES_SERVE_HEADLESS=1` so `mount_spa()` disables the SPA even if a stray `web_dist/` exists — only the JSON-RPC/WS/API surface is reachable). `dashboard` and `serve` share `cmd_dashboard`/`start_server` but are independent surfaces — neither launches the other. The one exception is a backward-compat *fallback*: `serve` is newer, so the desktop spawn (`electron/backend-command.ts` + `backendSupportsServe()` in `electron/main.ts`) detects whether the resolved runtime registers `serve` and, only when it does not (an older managed install / PATH `hermes` the app hasn't updated yet), rewrites the argv to the legacy `dashboard --no-open`. Without that, a new app against an un-upgraded runtime would crash on an unknown subcommand and brick every mid-upgrade user. It does NOT embed `hermes --tui` — it has its own composer, transcript, and slash-command pipeline. For scoped Desktop architecture, state, resolver, transport, and testing rules, read `apps/desktop/AGENTS.md`.

It does NOT embed `hermes --tui` — it has its own composer, transcript, and slash-command pipeline. Route desktop bugs to the `hermes-desktop-app-work` skill, not `hermes-dashboard-work`.
 
 **Slash commands in the desktop app are curated client-side, then dispatched to the backend.** The pipeline:
 
 - **Backend already provides everything.** `tui_gateway/server.py` `commands.catalog` (empty-query list) and `complete.slash` (typed-query completions) both include built-in commands, user `quick_commands`, AND skill-derived commands (`scan_skill_commands()` / `get_skill_commands()`). The desktop app does not need a new RPC to see skills.
-- **The renderer curates via `apps/desktop/src/lib/desktop-slash-commands.ts`.** This is the load-bearing file. It holds `DESKTOP_COMMAND_SPECS` (the built-ins and their Desktop surfaces) plus `NO_DESKTOP_SURFACE` block-lists for terminal-only / messaging-only / picker-owned / settings-owned / advanced commands that should NOT clutter the desktop popover.
+- **The renderer curates via `apps/desktop/src/lib/desktop-slash-commands.ts`.** This is the load-bearing file. It holds `DESKTOP_COMMANDS` (the ~19 built-ins shown in the palette) plus block-lists for terminal-only / messaging-only / picker-owned / settings-owned / advanced commands that should NOT clutter the desktop popover.
   - `isDesktopSlashCommand(name)` — gates **execution**. Returns true for built-ins AND for any non-built-in (skill / quick command), so typed extension commands run.
   - `isDesktopSlashSuggestion(name)` — gates **discovery/completion**. Used by BOTH completion paths in `app/chat/composer/hooks/use-slash-completions.ts` (empty-query catalog filter + typed-query `complete.slash` filter) and by `filterDesktopCommandsCatalog`.
   - `isDesktopSlashExtensionCommand(name)` — true when the command is NOT a known Hermes built-in (i.e. a skill or user quick command). Both suggestion and catalog-filter paths allow extensions through so skill commands surface in the palette. (Added when fixing "skill commands missing from the desktop slash palette" — the curated allow-list was silently dropping every skill/quick command from completions even though they executed fine when typed.)
-- **Dispatch** lives in `app/session/hooks/use-prompt-actions/slash.ts` (`runSlash`): built-ins that the desktop owns (`/skin`, `/help`, `/new`, …) are handled locally or via `commands.catalog`; everything else goes to `slash.exec`, falling back to `command.dispatch` (which the gateway resolves into skill / alias / exec directives). A skill command resolves to `{type: "skill", message}` and is submitted as a normal prompt.

-**Rule:** the desktop slash palette's curation is about hiding noise (terminal-only / messaging-only built-ins), NOT about hiding user-activated extensions. Skill commands and `quick_commands` are extensions the backend surfaces — they belong in completions. If you tighten `desktop-slash-commands.ts`, keep `isDesktopSlashExtensionCommand` flowing into both the suggestion and catalog-filter paths. Tests: from `apps/desktop`, run `npx vitest run src/lib/desktop-slash-commands.test.ts` (workspace dependencies are installed at the repo root).

-**Why it's actively harmful, not just weak:**
-
-- It passes when the implementation is subtly broken (the regex matches a

-  refactor changes formatting, variable names, or control flow with
-  identical runtime behavior. Both directions of failure are wrong.
-- It can't be run against a built/bundled/minified artifact, so it silently
-  stops testing anything the moment code moves, gets renamed, or a
-  dependency reformats it.
-- It actively blocks refactors: reviewers see "keeps a pattern intact" tests
-  fail during pure structural cleanup with no behavior change, and either
-  hand-wave the failure (dangerous) or waste time updating regexes that add
-  nothing (waste).
-- It gives false confidence. a green suite full of source-regex tests
-  looks like coverage but has never once executed the code path it claims
-  to guard.
-
-**Do not write:**
-
-```ts
-const source = fs.readFileSync(path.join(__dirname, 'main.ts'), 'utf8')
-
-test('backend spawn hides the Windows console', () => {
-  assert.match(source, /spawn\(\s*backend\.command,\s*backend\.args[\s\S]{0,300}hiddenWindowsChildOptions/)
-})
-```
-
-**Do write — extract the logic into a small pure/DI-testable function and
-call it for real:**
-
-```ts
-// backend-spawn.ts
-export function hiddenWindowsChildOptions(options: SpawnOptionsLike = {}, isWindows = process.platform === 'win32') {
-  if (!isWindows || 'windowsHide' in options) return options
-  return { ...options, windowsHide: true }
-}
-
-// backend-spawn.test.ts
-test('windowsHide defaults to true on Windows, is left alone elsewhere', () => {
-  assert.equal(hiddenWindowsChildOptions({}, true).windowsHide, true)
-  assert.equal(hiddenWindowsChildOptions({}, false).windowsHide, undefined)
-  assert.equal(hiddenWindowsChildOptions({ windowsHide: false }, true).windowsHide, false)
-})
-```
-
-If the logic lives inline in a god-file (`main.ts`, `cli.py`,
-`gateway/run.py`) and extracting it feels disruptive: that's the actual
-signal to do the extraction, not to regex around it.

-dashboard analytics blind to aux model spend (issue #23270).
-
-Instead of threading ``session_db``/``session_id`` parameters through every
-aux call site, the agent loop publishes them here (mirroring the Nous Portal
-conversation context in ``agent.portal_tags``) and the auxiliary client
-records usage at its single response-validation chokepoint.
-
-ContextVar semantics give us the right isolation for free:
-
-* concurrent agents in one process (gateway sessions, delegate subagents)
-  never see each other's accounting context;
-* worker threads spawned via ``tools.thread_context.propagate_context_to_thread``
-  (MoA fan-out, background review) inherit the parent turn's context;
-* asyncio tasks inherit the context of the code that created them.
-
-MoA reference/aggregator slots are explicitly EXCLUDED from recording:
-``agent/conversation_loop.py`` already folds MoA advisor usage and cost into

-"""Bounded reads of HTTP error response bodies.
-
-When a provider returns a non-OK status on a *streaming* request, Hermes reads
-the response body to build a useful diagnostic error. A bare ``response.read()``
-on a streaming httpx response is unbounded in two dangerous ways:
-
-1. A server can declare (or stream) an arbitrarily large body, so the read can
-   balloon memory.
-2. A server can open the body and then stall forever (no ``Content-Length``,
-   no further bytes), so the read hangs the agent indefinitely.
-
-Both are realistic against a misbehaving proxy, a hijacked endpoint, or a
-provider having a bad day. The diagnostic body is only ever shown to the user
-truncated to a few hundred characters, so reading megabytes — or blocking
-forever — buys nothing.
-
-``read_streaming_error_body`` bounds the read to a byte cap and enforces a
-hard wall-clock deadline, returning the decoded text snippet. Callers pass the
-returned text into their existing error builders instead of touching
-``response.text`` (which would be unbounded / would raise after a partial
-stream read).
-
-A subtlety the implementation must respect: ``httpx``'s ``iter_bytes()`` blocks
-*inside* the C/socket read while waiting for the next chunk. A wall-clock check
-placed only between yielded chunks cannot interrupt a server that opens the
-body and then stalls mid-chunk — control never returns to Python until httpx's
-own (often 30s+) read timeout fires. To guarantee a bounded stop regardless of
-socket behavior, the read runs on a daemon worker thread and the caller waits
-on it with a hard deadline; on timeout we close the response (which unblocks /
-cancels the read) and return whatever partial bytes were collected.
-
-Ported and adapted from openclaw/openclaw#95108 ("bound Anthropic error
-streams"), generalized to cover Hermes's three streaming error-body sites
-(native Gemini, Gemini Cloud Code, Antigravity Cloud Code).

-"""Secret-source contract: the ABC every secret backend implements.
-
-A *secret source* resolves credentials from an external secret manager
-(Bitwarden Secrets Manager, 1Password, an OS keystore, a user script, ...)
-into environment-variable-shaped values at process startup, AFTER
-``~/.hermes/.env`` has loaded and BEFORE the rest of Hermes reads
-``os.environ``.
-
-Scope of the contract (deliberate, please do not widen):
-
-* **Read-only.**  Sources resolve refs → values.  There is no write-back
-  ("save this key to your vault"), no arbitrary secret objects, and no
-  mid-session secret API.  If a future need for rotation/refresh appears
-  it will arrive as a versioned optional hook — do not bolt it on.
-* **Startup-time, synchronous.**  ``fetch()`` is called once per process
-  (per HERMES_HOME) by the orchestrator in
-  :mod:`agent.secret_sources.registry`, which enforces a wall-clock
-  timeout around it.  Sources must not spawn background refreshers.
-* **Never raises, never prompts.**  ``fetch()`` returns a
-  :class:`FetchResult` — errors go in ``result.error`` with a
-  machine-readable :class:`ErrorKind`.  Interactive auth belongs in the
-  source's CLI ``setup`` flow, never on the startup path (non-TTY
-  gateway/cron startup must never block on stdin).
-* **Sources fetch; the orchestrator applies.**  A source returns the
-  name→value mapping it *would* contribute.  Precedence (mapped-beats-bulk,
-  first-wins, ``override_existing``, protected vars), conflict warnings,
-  provenance tracking, and the actual ``os.environ`` writes are owned by
-  the orchestrator so no backend can get them wrong.
-
-Versioning: ``SECRET_SOURCE_API_VERSION`` gates plugin compatibility.
-New *optional* hooks with default implementations do not bump it;
-required-signature changes do, and the registry skips (with a warning)
-sources built against a different major version instead of crashing
-startup.

-"""1Password (`op` CLI) secret source.
-
-Resolve provider credentials from 1Password ``op://vault/item/field``
-references at process startup so they don't have to live in plaintext in
-``~/.hermes/.env``.
-
-Design summary
---------------
-
-* Users map environment-variable names to official 1Password secret
-  references in ``secrets.onepassword.env``::
-
-      secrets:
-        onepassword:
-          enabled: true
-          env:
-            OPENAI_API_KEY: "op://Private/OpenAI/api key"
-            ANTHROPIC_API_KEY: "op://Private/Anthropic/credential"
-
-* After ``.env`` loads, each reference is resolved with a single
-  ``op read -- <reference>`` call and injected into ``os.environ`` (the
-  same point in startup as the Bitwarden source).
-* Authentication is whatever the user's ``op`` CLI already uses — a
-  service-account token (``OP_SERVICE_ACCOUNT_TOKEN``) for headless boxes,
-  or a desktop/interactive session (``OP_SESSION_*``).  Hermes never
-  authenticates on the user's behalf; it shells out to an already-trusted,
-  already-authenticated CLI.
-* Failures NEVER block startup.  A missing ``op`` binary, expired auth, a
-  bad reference, or a permission error each surface a one-line warning and
-  Hermes continues with whatever credentials ``.env`` already had.
-
-The atomic-write / ``0600`` / TTL cache mechanics are shared with the other
-backends via :mod:`agent.secret_sources._cache` — successful, complete pulls
-are cached in-process and on disk under ``<hermes_home>/cache/op_cache.json``
-so back-to-back short-lived ``hermes`` invocations don't re-shell ``op`` for
-every reference.  The disk file holds only resolved secret *values*; auth
-material is fingerprinted, never stored.

-* per-source wall-clock timeout enforcement around ``fetch()``
-* precedence: mapped sources beat bulk sources; within a shape,

-* ``override_existing`` semantics (may beat .env/shell, never another

-* cross-source conflict warnings (shadowed claims are always surfaced)
-* provenance: which source supplied every applied var

-"""Upload a Hermes session transcript to Hugging Face as an agent trace.
-
-Hermes stores sessions in its own SQLite store (``hermes_state.SessionDB``),
-so we reconstruct the conversation and emit it in the **Claude Code JSONL**
-shape — one of the three formats the Hugging Face Agent Trace Viewer
-auto-detects (Claude Code / Codex / Pi). No dataset-side preprocessing is
-needed; the Hub tags the dataset ``agent-traces`` and opens it in the viewer.
-
-Docs: https://huggingface.co/docs/hub/agent-traces
-
-Design notes
-------------
-* **Zero LLM turn.** This is a deterministic export — it never spends a
-  model call. The ``hermes trace upload`` subcommand calls
-  :func:`upload_session_trace` directly.
-* **Private by default.** Traces can contain prompts, tool output, local
-  paths, and secrets. The dataset is created private and every text body
-  is passed through Hermes' secret redactor (``force=True``) unless the
-  caller explicitly opts out with ``redact=False``.
-* **Never raises.** Returns a user-facing status string so command
-  handlers can echo it straight back to the user. Programmatic callers
-  that need the URL can use :func:`build_trace_jsonl` + :func:`_do_upload`
-  directly.
