Phase 1 of audiobooks integration - establishes local storage foundation:
- Add Drift (SQLite) database with tables for profiles, recently played,
library cache, and sync metadata
- Add DatabaseService singleton for database access
- Add ProfileService for automatic user profile management
- Profiles auto-created from MA authentication (username) or manual entry
- Migration support for existing ownerName to profile
- Hook profile creation into MA login flow and login screen
- Update CI workflow to generate Drift code with build_runner
- Add comprehensive implementation plan document
This enables:
- Per-user recently played isolation (no cross-contamination)
- Fast app startup with cached data
- Foundation for audiobook progress tracking
