feat(governed): protected-main status producer pipeline (OPTION A)

Establish a compliant status producer pipeline to unblock protected-main's
9 required status contexts (py-compile, git-diff-check, secret-scan,
autonomy-unit-tests, autonomy-smoke-tests, reconciliation-contract,
release-state-machine, campaign-approval-gate, signer-validator-contract).

- status_publisher: idempotent (effect_id), SUPPRESS_NOOP, RECONCILE,
  capability-minimal (status_publish only), append-only evidence store.
- status_orchestrator: exact-head-SHA binding, stale-SHA protection,
  merge eligibility gated on producer verdict + confirmed publish
  (existing_state_differs never credited green).
- status_evidence_contract: evidence schema, effect_id, N/A contract binding.
- producer_scope_classifier: campaign/signer applicability, fail-closed.
- status_producers/: 9 thin wrappers reusing existing validators (gitleaks,
  reconciliation, ReleaseStateMachine, campaign gate, signer contract).
- transport/broker: add publish_status_for_sha (exact SHA) + read_statuses.
- status_pipeline_entry: S6 trigger skeleton with optional scope/smoke
  injection (fail-closed when absent; no fabricated success).
- tests: 65 passing (engineer + QA adversarial + regression).

No forgery of success, no blanket green reporter, no weakening of
branch protection. Reuses existing Gitea machine broker + validators.

+"""QA independent verification for the protected-main status pipeline.
+
+Written by QA (yan-guoguan) with a fresh-eyes mandate: hunt for red-line
+violations / merge-eligibility spoofing that Engineer's 27-item suite did not
+cover.  Fully local: fake broker + temp evidence store, no real Gitea/gitleaks.
+
+Targeted adversarial cases:
+  C1. FAIL/UNKNOWN verdict but a conflicting existing "success" status on the
+      same SHA+context plus an unknown POST -> RECONCILE reports the leftover
+      status's state.  merge_eligible MUST be False (a FAIL context must never
+      be credited as green because a stray success status exists).
+  C2. RECONCILE exhausted (both read attempts fail) -> action UNKNOWN, state
+      != success, and merge_eligible False at orchestrator level.
+  C3. One producer raises a runtime exception -> orchestrator converts it to
+      UNKNOWN (never success) and the other 8 producers still run.
+  C4. Idempotency: same effect replayed twice -> 2nd is SUPPRESS_NOOP and the
+      evidence store is not duplicated.
+  C5. N/A but scope facts incomplete/ambiguous -> classify_na raises -> producer
