feat(02-03): crash recovery detection and user notification
- Enhance interruptStaleRuns to return count and mark tasks as blocked - Add lastInterruptedCount property for bootstrap recovery check - Add getInterruptedRunsForRecovery query method - Add retryInterruptedTask, dismissInterruptedTask, markInterruptedTaskFailed actions - Add recovery-needed IPC event emission in bootstrap between heartbeat and resume - Create ipc-recovery-handlers.ts with retry/dismiss/fail IPC handlers - Register recovery handlers in domain handler chain - Expose recoveryRetry, recoveryDismiss, recoveryFail in preload API - Add recovery method types to DesktopApi contract - Create RecoveryBanner component with retry/cancel per interrupted task - Integrate RecoveryBanner at top of Dashboard view - Add crash recovery unit tests (9 tests)
