fix(watchdog): add HEAD-recheck + settling delay to suppress cancel-cascade false-positives

Adds a 90s settling window + HEAD-recheck before filing `[main-red]` issues. After initial red detection, the watchdog now: 1. Re-fetches HEAD SHA — if main moved on (new commit landed mid-tick), skip-file and let the next cron tick re-evaluate. 2. Re-fetches combined status on the same SHA — if it recovered (transient cancel-cascade rolled forward to success on retry), skip-file. Both skip paths emit distinct Loki events (`main_red_skipped_head_drift`, `main_red_skipped_recovered`) so obs queries can track filter activity vs the genuine `main_red_detected` path. Background — 7 false-positive `[main-red]` issues filed in 24h (mc#1597, #1605, #1609, #1613, #1626, #1627, #1630), all closed in triage 2026-05-21 04:55 as 6 cancel-cascade + 1 emission artifact, zero real regressions. Empirical 7-day DB sweep on 2026-05-20 showed that of 702 `action_run.status=3` (Cancelled) entries that wrote a `commit_status.state='failure'` row, only 76 (~11%) carried description=`'Has been cancelled'` (the existing mc#1564 filter's match string). 89% used `'Failing after Ns'`, indistinguishable from real `status=2` (Failure) at the commit-status layer. The canonical filter (only file when `action_run.status=2`) is not reachable from a Gitea Actions runner — Gitea 1.22.6 exposes no REST endpoint for `action_run.status` (probed empirically: `/api/v1/.../actions/runs/{id}`, `/jobs/{id}`, `/tasks/{id}` all return HTTP 404; swagger.v1.json contains no read endpoints for action runs). The SPA backend requires a session CSRF token, and DB access (`mol_action_status`, `docker exec ... psql`) lives only on the operator host. The HEAD-recheck is the strongest signal a runner can produce without that endpoint, and it caught all 7 of the mc#1597..1630 false-positives in offline replay (HEAD had moved past each of the 7 SHAs by the time the issue filed). The PR also adds `_resolve_action_run_status(target_url)` as an extensibility hook returning None today; when Gitea >=1.23 or an op-host proxy exposes the status endpoint, the function body can be filled in without changing callers. Tests (4 new + 1 hook test): - `test_head_recheck_skips_file_when_head_moved` — SHA_A initial → SHA_B on recheck → no POST. - `test_head_recheck_skips_file_when_recheck_status_recovered` — failure → success on same SHA → no POST. - `test_head_recheck_files_when_still_red_after_settling` — over-filter regression guard: persistent red MUST file. - `test_head_recheck_skips_when_initial_was_only_cancel_cascade` — cancel-cascade filter ordering guard. - `test_resolve_action_run_status_returns_none_on_no_endpoint` — pins the extensibility-hook return contract. An autouse `_stub_time_sleep` fixture is added so the existing integration-style tests (`test_red_detected_opens_issue` et al.) don't each block 90s on the new sleep call — pre-fix suite ran ~0.1s; with the bare implementation it took >4 minutes (the stub keeps the suite fast and deterministic without per-test patching). 41 tests pass in 0.15s. `--dry-run` against live Gitea returns the correct PENDING/no-action result on the current `main` head.

-#   2. The context this workflow emits is
-#      `ci-arm64-advisory / fast-checks (pull_request)`. That string is
-#      DELIBERATELY NOT present in, and this PR does NOT add it to:
-#        - branch_protections/{main,staging}.status_check_contexts
-#          (DB-verified pb 86/75 = exactly
-#           ["CI / all-required (pull_request)",
-#            "sop-checklist / all-items-acked (pull_request)"])
-#        - audit-force-merge.yml REQUIRED_CHECKS env
-#        - ci.yml `all-required` sentinel's hardcoded `required[]` list
-#      Branch protection therefore never waits on this context. If the
-#      Mac runner is absent / offline / removed, this workflow's status
-#      simply never appears — and because nothing requires it, every
-#      merge proceeds exactly as it does today. There is no path by
-#      which a missing/red arm64 status blocks a merge.
-#
-#   3. `continue-on-error: true` on the job — even a genuine arm64-only
-#      failure (toolchain drift, arch-specific test flake) is surfaced
-#      as information, never as a merge blocker, for the duration of
-#      the pilot.
-#
-#   4. The job carries a `github.event_name` `if:` gate. Beyond its
-#      functional purpose this also keeps the job OUT of
-#      `ci-required-drift.py:ci_job_names()` (which excludes
-#      `github.event_name`/`github.ref`-gated jobs), so the hourly
-#      ci-required-drift sentinel's F1 ("job not under sentinel needs")
-#      cannot ever flag this advisory job. F2/F3 are untouched because
-#      this context is absent from BP and from REQUIRED_CHECKS.
-#      `lint-bp-context-emit-match` only fails on BP→emitter gaps; an
-#      emitter without a BP context is explicitly informational there.
-#
-# === RUNNER TARGETING ===
-#
-# The Mac runner is `hongming-pc-runner-1`. The bare `self-hosted`
-# label is POLLUTED in this Gitea instance: molecule-runner-1..20
-# (the contended amd64 pool) also advertise `self-hosted`. Targeting
-# bare `self-hosted` would route back onto the very pool we are trying
-# to relieve — and onto amd64 hardware. We therefore require an
-# AND-set of labels that ONLY the Mac satisfies. `macos-self-hosted`
-# is Mac-exclusive (the amd64 pool does not carry it). Until the
-# label-install burst (a10862b2) lands `self-hosted`+`macos-self-hosted`
-# on the Mac, the runner's current unique label `hongming-pc-laptop`
-# is also listed; AND-semantics over the labels a runner advertises
-# means a job requiring [self-hosted, macos-self-hosted] can ONLY be
-# claimed once the Mac advertises both. If neither label set is yet
-# present on the Mac, the workflow stays queued harmlessly and is
-# garbage-collected by the normal stale-run reaper — it blocks nothing
-# (see safety contract point 2).
-#
-# === ROLLBACK ===
-#
-# Delete this single file (`git rm .gitea/workflows/ci-arm64-advisory.yml`)
-# and merge. No branch-protection edit, no ci.yml edit, no
-# REQUIRED_CHECKS edit is required to roll back, because none were made
-# to roll forward. Zero blast radius either direction.

-## Multiple Workspaces From One Local MCP Bridge
-
-The standalone runtime package includes `molecule-mcp`, a local MCP bridge for
-external agents such as Claude Code, Codex, Hermes, and other tools that run
-outside the platform container fleet. One local bridge can serve multiple
-external workspaces by setting `MOLECULE_WORKSPACES`:
-
-```json
-[
-  {
-    "id": "workspace-id-local-to-hongming-org",
-    "token": "...",
-    "platform_url": "https://hongming.moleculesai.app"

-  {
-    "id": "different-workspace-id-local-to-agents-team-org",
-    "token": "...",
-    "platform_url": "https://agents-team.moleculesai.app"
-  }
-]
-```
-
-`platform_url` is the tenant routing key. The bridge registers, heartbeats,
-polls inboxes, and sends outbound A2A calls against the URL attached to the
-workspace that is doing the work.
-
-Do not add `org_id` to this config. The tenant already comes from
-`platform_url`, and the bearer token is issued by that tenant. Workspace IDs
-also do not need to be shared across orgs; each tenant can return its own
-workspace ID and token for the same local agent process.

-## Multi-Tenant Local MCP Bridge
-
-For local MCP-driven agents, use the standalone runtime's `molecule-mcp`
-entrypoint. A single local bridge can serve multiple external workspaces by
-setting `MOLECULE_WORKSPACES`:
-
-```json
-[
-  {
-    "id": "workspace-id-local-to-acme",
-    "token": "...",

-    "token": "...",
-    "platform_url": "https://ops.moleculesai.app"
-  }
-]
-```
-
-`platform_url` selects the tenant for registration, heartbeat, inbox polling,
-and outbound A2A routing. `org_id` is not required in this config, and the
-workspace IDs do not need to match across tenants.
