gpt-engineer-app[bot] 34dbe2e262 Implement Phase 4: Transaction Resilience ...

This commit implements Phase 4 of the Sacred Pipeline, focusing on transaction resilience. It introduces:

- **Timeout Detection & Recovery**: New utilities in `src/lib/timeoutDetection.ts` to detect, categorize (minor, moderate, critical), and provide recovery strategies for timeouts across various sources (fetch, Supabase, edge functions, database). Includes a `withTimeout` wrapper.
- **Lock Auto-Release**: Implemented in `src/lib/moderation/lockAutoRelease.ts` to automatically release submission locks on error, timeout, abandonment, or inactivity. Includes mechanisms for unload events and inactivity monitoring.
- **Idempotency Key Lifecycle Management**: A new module `src/lib/idempotencyLifecycle.ts` to track idempotency keys through their states (pending, processing, completed, failed, expired) using IndexedDB. Includes automatic cleanup of expired keys.
- **Enhanced Idempotency Helpers**: Updated `src/lib/idempotencyHelpers.ts` to integrate with the new lifecycle management, providing functions to generate, register, validate, and update the status of idempotency keys.
- **Transaction Resilience Hook**: A new hook `src/hooks/useTransactionResilience.ts` that combines timeout handling, lock auto-release, and idempotency key management for robust transaction execution.
- **Submission Queue Integration**: Updated `src/hooks/useSubmissionQueue.ts` to leverage the new submission queue and idempotency lifecycle functionalities.
- **Documentation**: Added `PHASE4_TRANSACTION_RESILIENCE.md` detailing the implemented features and their usage.
