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.
