Complete LOOP-WP-0005: DEC-008 weekly operate promotion

Operator override per ADR-003 closes the stabilize observation window
early (day 2/14) and promotes all four loops to weekly Mon crons.
Activity definitions renamed coulomb-daily-* → coulomb-weekly-*;
cadence.yml, dashboard, SCOPE, and health records updated.
activity-core definition sync still required on operator side.

+LOOP-WP-0004 — aggregates first-order loop health for regulator sessions.
+Weekly `0 11 * * 1` aligned with regulator session (DEC-008).

+```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 7d 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`.
