refactor(status): decommission entire STATUS flow — STATUS.local.md + central STATUS.md retired, replaced by local.json todos[] + dashboard count (TDPLAN-0007)

Cross-branch coordinated change. Per-branch STATUS.local.md (13) + central
STATUS.md deleted; all prompts/docs/skills/hooks/footer/scaffolding scrubbed.
Status-sync engine kept intact-but-inert (trigger registry unwired, 3 lines).
Replacement: operational todos[] in .trinity/local.json (@memory schema, capped,
rollover-exempt), pushed to all 13 branches + surfaced as dashboard todo_count.

Owners: memory (schema+global push+template), prax (dashboard todo_section +
engine dormant), trigger (unwire), aipass (init scaffolding), spawn (template
delete + todos[] seed), hooks (compact recovery), ai_mail (footer), seedgo
(_RUNTIME_ARTIFACTS cleanup), devpulse (scrub+delete+assemble).
