- Add `index_build_owner` and `index_lease_expires_at` columns to workspaces table for lease-based concurrency control
- Implement 60-second indexing leases with 15-second heartbeat refresh to detect stale/crashed indexers
- Allow new indexers to claim expired leases automatically without manual intervention
- Validate owner token on lease refresh and release operations to prevent unauthorized takeover
- Clear lease
