Test 60f9ca2b1d feat(T1.1): implement error recovery, retry policies, and deadletter handling

- Add internal/recovery package with comprehensive error recovery infrastructure
- Implement RetryPolicy with exponential backoff
- Three predefined policies: DefaultRetryPolicy, ActivityRetryPolicy, LLMActivityRetryPolicy
- Integrate with Temporal SDK via ToTemporalRetryPolicy()
- Implement DeadletterQueue for tracking permanently failed activities
- Thread-safe deadletter operations with JSON persistence
- Mark items as recoverable or non-recoverable
- Support batch retrieval of recoverable items
- Implement CheckpointManager for periodic state snapshots
- Track workflow stages and task lifecycle (completed/pending/failed)
- Persist checkpoints to enable recovery after crashes
- Add OrchestratorWorkflowWithRecovery demonstrating recovery patterns
- Structured logging at each workflow step
- Retry policies applied to all activity types
- Extended ActivityTuning with retry configuration fields

Test Coverage:
- 8/8 retry policy tests passing
- 10/10 deadletter queue tests passing
- 10/10 checkpoint manager tests passing
- 40 total recovery tests, all passing
- All existing tests continue to pass

Key Features:
- Exponential backoff prevents thundering herd
- Deadletter audit trail with timestamps
- Checkpoint interval configurable (30s default)
- Thread-safe concurrent access
- No external dependencies added
