Implement calendar synchronization features enabling bidirectional syncing of calendar events and tasks.

Purpose: Allow seamless integration of calendar events with weekly task view and enable users to manage calendar connections. Output: Bidirectional synchronization logic, sync API endpoint, and calendar settings UI.

Implement Bidirectional Sync Logic src/lib/calendar-sync.ts Create a TypeScript module that implements the core synchronization logic: - Determine which calendars are connected and active - Fetch events from calendar APIs - Identify tasks that need to be imported from calendars - Identify calendar events that need to be converted to tasks - Handle conflicts in naming, dates, or other attributes - Handle updates and deletions from both sides

Reference calendar data structures from Phase 2 and API patterns from Phase 1. npm test passes and the module exports syncCalendarEvents and syncCalendarTasks functions without error Module exports syncCalendarEvents and syncCalendarTasks functions that handle bidirectional sync

Create Calendar Sync API Endpoint src/app/api/calendar/sync/route.ts Create a POST API endpoint that: - Validates user authentication - Triggers the calendar synchronization process - Calls the sync logic from calendar-sync.ts - Returns appropriate status codes and responses - Handles errors gracefully with appropriate messaging

Follow the API endpoint pattern established in Phase 2 and authentication flow from Phase 1. curl -X POST http://localhost:3000/api/calendar/sync returns 200 with successful sync status Endpoint successfully triggers sync process and returns status JSON

Verify that all components work in concert: 1. Manual sync button triggers the sync API endpoint 2. Sync process retrieves events from calendars 3. Events are properly imported as tasks (when applicable) 4. Tasks can be exported to calendars (when configured) 5. Settings persist between sessions

<success_criteria>

• Users can manage calendar connections and sync settings from UI
• Bidirectional synchronization works between calendar events and tasks
• Events are properly imported from calendars to tasks
• Tasks can be created from calendar events when configured </success_criteria>
