fix(ci): make the validate job actually able to run — it never had

ci.yml has been invalid YAML since introduction: the 'Config validation'
and old inline checks dedented out of their run:| block scalar, so Gitea
could never parse the workflow — CI never ran on any PR despite
CI_STATUS.md claiming 'Active'. The old 'No secrets check' also always
passed (|| echo swallows the grep hit) and never scanned *.yml — where
six embedded credentials were living.

- validation logic moved to ci_check.py (testable locally: python3 ci_check.py all)
- secrets check now FAILS on embedded http-basic URLs and long api_keys,
  across .py/.ts/.yaml/.yml/.cjs/.sh, with placeholder allowlist
- added workflow-YAML parse gate so this class of breakage can't recur
- py_compile steps no longer swallow errors with '|| echo skipped'
- removed ci.yml's duplicate deploy job: deploy.yml is the sole deploy
  pipeline (rc tags → Tanko canary only; stable → all agents). The ci.yml
  copy would have deployed Mumuni on rc tags too, breaking canary policy,
  and never ran anyway.
- CI_STATUS.md rewritten with the real state + caveats (history still
  contains the old creds — rotation is a server-side task)

 # CI Pipeline Status
-Status: Active
+
+**Last verified: 2026-09-25** — see PR "main security + truncate + CI repair".
+
+## Reality check (before that PR)
+`ci.yml` was **invalid YAML** — the inline `run: |` blocks for the config and
+secrets checks dedented out of their block scalar, so Gitea Actions could never
+parse the workflow. CI never ran on any PR, and this file's "Active" status was
+fiction. The old "No secrets check" also swallowed hits with `|| echo` (always
+green) and never scanned `.yml` files — which is where six embedded
+credentials were living.
+
+## Current pipeline
+| Trigger | Job | Checks |
+|---|---|---|
+| PR → main, push main, tag `v*` | `validate` | adapter + a2a `py_compile`; workflow YAML parse; `config.yaml.example`; secret scan; `bash -n scripts/deploy.sh` |
+| tag `v*` | `deploy` | Tanko canary + Mumuni via `scripts/deploy.sh` (native mode) |
+
+All validation logic lives in **`ci_check.py`** — run `python3 ci_check.py all`
+locally before pushing; it fails the check on real hits instead of echoing
+warnings.
+
+## Known caveats
+- The removed credentials still exist in git history (pre-July commits) —
+  rotating `abiba-bot`'s password is a **server-side** task, out of repo scope.
+- Runner availability (`zulip-runner` on CT 116) is not verifiable from agents
+  — the first green run after merge is the proof.
