feat(reconciliation): implement deterministic state reconciliation engine and post-commit hook

- Implement ReconciliationEngine in server/src/handlers/reconciliation.rs
- Auto-transition ADRs to implemented, resolve tech debts, and cascade task unblocking
- Ingest git commit events via POST /api/git/commit and scripts/git-reconcile.py post-commit hook
- Add universal pagination, search filtering, and keyboard navigation to dashboard
- Implement non-destructive task TTL expiry sweeper and gate verification
- Implements: ADR-0102, ADR-0103
