feat: advance LOOP-WP-0002/0003/0004 without activity-core blockers

Document event payload contract, draft disabled ActivityDefinitions for
CI/regulator/registry hygiene, initialize loop health snapshots and
regulator dashboard, record DEC-005 kaizen-stack promotion, and close
supplier-independent workplan tasks.

+LOOP-WP-0004 T03 — aggregates first-order loop health for regulator sessions.
+Cron `50 * * * *` runs after kaizen stack (08–10 daily) and quality sweep chain.

+```instruction
+id: append-health-snapshot
+description: |
+  For each loop in coulomb-loop/loops/*/cadence.yml, append one JSON line to
+  loops/<loop-id>/health.jsonl with:
+  - timestamp, phase, tasks_created (from hub), manual_rescues (bootstrap-log),
+    agent_success_rate (pilot metrics avg), false_positive_rate (estimate).
+  Regenerate loops/regulator/dashboard.md from last 24h of health.jsonl files.
+  If demotion trigger from state-machine.md fires, create urgent optimization task.
+```
+
+Keep `enabled: false` until instruction executor supports file-append actions.
+Manual collection documented in `loops/regulator/session-template.md` (T05).
