feat(android): add runtime starred plans management API

- Add updateStarredPlans() method to update plan IDs from TimeSafari app
  - Stores plan IDs in SharedPreferences for persistence
  - Integrated with TimeSafariIntegrationManager for prefetch operations
  - Includes comprehensive logging for debugging

- Add getStarredPlans() method to retrieve current stored plan IDs
  - Allows TimeSafari app to verify synchronization
  - Returns count and last update timestamp

- Update TimeSafariIntegrationManager to load starred plan IDs
  - Reads from SharedPreferences when building TimeSafariUserConfig
  - Used automatically by EnhancedDailyNotificationFetcher for API calls
  - Enables dynamic updates without requiring app restart

- Add TypeScript definitions for new methods
  - Includes JSDoc documentation for integration guidance
  - Matches Android implementation return types

- Create integration example for TimeSafari app
  - Shows how to sync plan IDs from account settings
  - Demonstrates star/unstar action handling
  - Includes verification and error handling patterns

This allows the TimeSafari app to dynamically update starred project
IDs when users star or unstar projects, without requiring plugin
configuration changes or app restarts. The stored IDs are automatically
used by the prefetch system to query for project updates.
