Closes #433

What changed

  • persist live snapshot content, per-section freshness/backoff, and revisions atomically in private SQLite state
  • coordinate workers with an expiring refresh lease and stale-while-revalidate reads
  • preserve cross-worker notification filtering and recover from cancellation, lease expiry, reboot, and state-store outages

Verification

  • strict RED/GREEN behavioral coverage for lease races, atomic publication, expiry recovery, wall-clock persistence, cooldown behavior, cancellation cleanup, private permissions, and store outages
  • python3 -m pytest tests/test_live_snapshot_store.py tests/test_live_snapshot.py tests/test_notification_read.py -q — 34 passed
  • python3 -m pytest -q — 840 passed
  • python3 -m compileall -q src tests
  • git diff --check
