fix(types): fix ty python env resolution + triage discord adapter

The .venv directory (created by uv run) contained Python 3.13 with no deps installed. ty auto-discovers .venv for module resolution, so it could not find discord.py, aiohttp, etc., producing ~1000 false "Module has no member" errors. Removing the stray .venv makes ty fall back to the nix env (Python 3.12 with all deps installed). Also set python-version = "3.12" in [tool.ty.environment] with a comment explaining why. ty diagnostics: 4,422 -> 3,385 (-1,037) Tests: 496 passed, 0 failed fix(nix): use python311 in dev shell (matches requires-python floor) Production venv still uses python312 (nixos-unstable default). The dev editable venv now uses python311 — the requires-python floor (>=3.11) — so ty type checking and local dev catch 3.12+-only syntax that wouldnt

+name: auto-fix lint issues & formatting
+
+# On push to main (or manual trigger), run `npm run fix` on each workspace
+# package and apply any changes via a PR.
+#
+# Fixable lint issues (import sorting, unused imports, curly braces, etc.) are
+# auto-corrected on merge so PRs aren't blocked by them. The PR-time eslint
+# check in typecheck.yml fails only when un-fixable errors remain.
+#
+# NOTE: AUTOFIX_BOT_PAT pushes DO trigger further workflow runs (unlike
+# secrets.GITHUB_TOKEN). The concurrency group (ts-autofix-${{ github.ref }})
+# with cancel-in-progress: true prevents an infinite loop — a re-triggered
+# 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.

+The CI change classifier (`scripts/ci/classify_changes.py`) runs specific jobs based on what files changed. A Python test that asserts
+about the contents of `package.json`, `package-lock.json`, `.ts`/`.tsx`
+source, or any other JS-side artifact will not run on a PR that only touches
+those files. This means a regression can go green on a PR and red on `main` (where the
+classifier fails open and runs everything).
+
+Any test that reads or asserts about `package.json`,
+`package-lock.json`, `tsconfig.json`, `.ts`/`.tsx`/`.js`/`.mjs`/`.cjs`
+source files configuration belongs in the JS (vitest) test suite, not in `tests/*.py`.

+"""Ambient session-accounting context for auxiliary LLM calls.
+
+Auxiliary calls (vision, compression, title generation, web_extract,

+session handle — so their token usage was historically discarded, leaving
+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.

+  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.

+ * Regression: the desktop Electron dependency must be an exact, consistent pin.

+ * changed its install mechanism mid patch-series:
+ *
+ *     electron 40.9.3 .. 40.10.2  -> @electron/get@^2 + extract-zip@^2  (pure JS)
+ *     electron 40.10.3 / 40.10.4  -> @electron/get@^5 +
+ *                                    @electron-internal/extract-zip@^1 (native napi)
+ *
+ * ``apps/desktop/package.json`` declared ``electronVersion: 40.9.3`` (the tested,
+ * JS-extract build) but pinned the dependency loosely as ``electron: ^40.9.3``.
+ * ``npm ci`` then resolved 40.10.3/40.10.4 — the new *native* extract-zip whose
+ * win32-x64 binding fails to ``dlopen`` on some Windows hosts
+ * (``ERR_DLOPEN_FAILED loading index.win32-x64-msvc.node``).
+ *
+ * These tests lock the contract that prevents that drift, without hard-coding the
+ * specific version (which is allowed to move):
+ *
+ * 1. the Electron dependency is an *exact* version (Electron Builder needs the
+ *    installed binary to match ``electronVersion`` / ``electronDist``), and
+ * 2. the dependency, ``build.electronVersion``, and the resolved lockfile entry
+ *    all agree — so ``npm ci`` installs exactly what the build packages.
