ci-hygiene guard: lockfile-only installs, pinned images, no host-port services (warn-only)

House rule 6 (09-23). The bridge now also posts windy-git/ci-hygiene on
every PR head (added lines) and default branch (whole files), scanning CI
workflows and Dockerfiles for: floating pip / uv pip installs (not -r,
not --no-deps, not exact pins), uv sync without --locked/--frozen,
npm install instead of npm ci (unless every package is exact-pinned),
yarn/pnpm without a frozen lockfile, :latest images and COPY lock* globs
(Windy Mail #147), and CI services publishing a HOST port (every job
shares one dind: Windy Mind runs 147/176 died on 5432). Warn-only;
CI_HYGIENE_MODE=block later. Allow-list ci/ci-hygiene-allow.yml (empty).

compute_guard's walker is now parameterised (line_fn / path_ok /
prefilter) so both guards share one scanner, cache and allow loader; the
bridge posts both through one _post_guard. Today: 95 issues in 21 repos;
windy-git, calendar, traveler, traveler-site clean.

+"""CI hygiene guard: installs come from a lockfile, never "latest" (house rule 6).
+
+A floating install lets CI test different versions than prod ships, and a
+rebuild silently changes prod. Windy Cloud's OpenAPI test failed on exactly
+that (fastapi 0.141.1 in CI vs 0.136.0 on the dev box) and all three Cloud
+cells floated in prod. Also flags services that publish a HOST port: every
+CI job shares one dind daemon, so two jobs publishing 5432 collide ("port is
+already allocated", Windy Mind runs 147/176).
+
+WARN-ONLY (`windy-git/ci-hygiene`, green + "⚠ WARN"); CI_HYGIENE_MODE=block
+turns it red once the lanes report clean. Scans CI workflow files and
+Dockerfiles only. PR heads: lines the PR adds. Default branch: every line.
+
+OK (not flagged):
+  pip / uv pip install  -r FILE (with or without --require-hashes), --no-deps,
+                        exact pins (tool==1.2.3), pip/setuptools/wheel upgrades
+  uv sync --locked | --frozen          npm ci
+  npm install pkg@1.2.3 (every package exact-pinned)
+  yarn install --frozen-lockfile / --immutable   pnpm install --frozen-lockfile
+Also flagged: `:latest` images (FROM / COPY --from / image: / docker://) and
+`COPY uv.lock* ...`-style globs that build without the lock (Windy Mail #147).
