MAESTRO: fix(db): prevent FK constraint failures on worker restart

Browse Source 
Cherry-picked source changes from PR #889 by @Et9797. Fixes #846.

Key changes:
- Add ensureMemorySessionIdRegistered() guard in SessionStore.ts
- Add ON UPDATE CASCADE migration (schema v21) for observations and session_summaries FK constraints
- Change message queue from claim-and-delete to claim-confirm pattern (PendingMessageStore.ts)
- Add spawn deduplication and unrecoverable error detection in SessionRoutes.ts and worker-service.ts
- Add forceInit flag to SDKAgent for stale session recovery

Build artifacts skipped (pre-existing dompurify dep issue). Path fixes (HealthMonitor.ts, worker-utils.ts)
already merged via PR #634.

/**
* Zombie Agent Prevention Tests
*
* Tests the mechanisms that prevent zombie/duplicate SDK agent spawning:
* 1. Concurrent spawn prevention - generatorPromise guards against duplicate spawns
* 2. Crash recovery gate - processPendingQueues skips active sessions
* 3. queueDepth accuracy - database-backed pending count tracking
*
* These tests verify the fix for Issue #737 (zombie process accumulation).
*
* Mock Justification (~25% mock code):
* - Session fixtures: Required to create valid ActiveSession objects with
* all required fields - tests actual guard logic
* - Database: In-memory SQLite for isolation - tests real query behavior
