jedarden 53506684b7 P3: Task Registry + Persistence — 14-table SQLite schema, Redis mirror, Helm validation
Implements the full 14-table task-store schema from plan §4 with both SQLite
and Redis backends sharing the TaskStore trait. Every §13/§14 advanced capability
consumes one or more of these tables.

SQLite backend:
- 3 migrations (001: tables 1-7, 002: tables 8-14, 003: task registry fields)
- WAL mode + busy_timeout for single-process concurrency
- Schema version tracking with SchemaVersionAhead guard
- Full CRUD + proptest round-trips on all 14 tables
- Restart resilience test: all data survives close/reopen cycle

Redis backend:
- Hash + _index SET pattern for O(cardinality) iteration (no SCAN)
- TTL-based expiration for sessions, idempotency, admin_sessions
- SET NX/XX for leader lease CAS operations
- Sorted sets for canary_runs with auto-prune
- Rate limiting keys for search_ui and admin_login
- CDC overflow buffer with byte-budget trimming
- Scoped key rotation coordination (observe/check pattern)
- Pub/sub for admin session revocation propagation
- testcontainers integration tests for all 14 tables + extras

Helm chart:
- values.schema.json enforces redis backend when replicas > 1
- ESO ExternalSecret template for OpenBao integration
- Updated values with secret inventory and rate limiting config

Config validation:
- replication_factor/replica_groups > 1 requires redis
- HPA enabled requires redis
- CDC overflow=redis requires redis task store
- Leader election required when replica_groups > 1
- CSP/CORS wildcard rejection
