feat(skills): add optional weather skill

Current conditions + multi-day forecasts via the keyless Open-Meteo
APIs (geocoding + forecast). Pure-stdlib script (urllib/json/argparse),
metric/imperial units, text or JSON output, WMO code mapping.
Inspired by the most-installed community weather skill; implemented
first-party from the Open-Meteo docs.

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

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

+# (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

+### Where to place what tests
+
+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`.

+"""Shared dollar-denominated usage model for the billing/subscription surfaces.
+
+The single source of truth behind the ``/usage`` and ``/subscription`` usage
+bars (TUI + CLI). User feedback (Jun 2026): the terminal surfaces show
+**dollars**, never "credits", and every usage bar must make the monthly
+subscription allowance and separately-purchased top-up dollars distinctly
+visible.
+
+Data source: the NAS account-info fetch (``NousPortalAccountInfo``), whose
+``paid_service_access_info`` carries the three dollar magnitudes we render
+(despite the legacy ``*_credits`` field names, these are USD floats):
+
+  - ``subscription_credits_remaining``  -> plan dollars left this month
+  - ``purchased_credits_remaining``     -> top-up dollars left (rolls over)
+  - ``total_usable_credits``            -> total spendable
+
+plus ``subscription.monthly_credits`` (the plan's monthly $ allowance, the
+denominator for the "% used" plan bar) and ``current_period_end`` (renewal).
+
+Design: two SEPARATE bars (decided with the user) rather than one crammed
+three-segment bar — at terminal widths three same-glyph density segments are
+unreadable. The plan bar is "spent vs allowance this month" (carries % used);
+the top-up bar is "money you bought, doesn't expire". Each gets full
+resolution and a single fill glyph, so the bar is never ambiguous and never
+relies on color.
+
+Fail-open everywhere: any missing/non-finite field degrades to fewer bars or a
+magnitudes-only view; a logged-out / unreachable portal yields
+``available=False`` and the surface shows nothing.

 All of that is *prologue* — it runs once per turn, has no back-references into the
 loop, and produces a fixed set of values the loop then consumes. ``TurnContext``
