Merge PR #388: Daily Workflow Integration & Enhanced Reliability

- Resolve merge conflicts in backend/services/today_workflow_service.py and frontend/src/stores/workflowStore.ts
- Backend: Keep robust handling for both dict and object types in TaskProposal conversion
- Backend: Combine dependencies coercion with task metadata normalization
- Frontend: Implement graceful fallback pattern (try server first, then local generation on unavailability)
- Add provenanceSummary integration from server responses
- Ensure degraded mode handling with appropriate messaging
