Remove the deprecated "newer_wins" strategy from the conflict resolver
as CRDT is now the default and validated approach. The system now uses
only "crdt", "server_wins", and "local_wins" strategies.

Add one-time migration script to convert existing local IndexedDB
entities to Automerge CRDT documents. Includes:
- Migration with idempotency check (runs only once)
- Batch processing option for large datasets
- Progress callback for UI feedback
- Unit tests for migration logic

Add comprehensive test suite covering multi-device concurrent editing:
- Two devices editing different fields (no conflicts)
- Two devices editing same field (deterministic resolution)
- Concurrent edit and delete scenarios
- Card FSRS field concurrent updates
- Incremental sync simulation
- Three-way merge scenarios
- Serialization roundtrip with concurrent edits
- Edge cases (null handling, rapid edits)
- Offline queue simulation

The ConflictResolver now defaults to CRDT strategy which uses Automerge
to merge local and server documents during sync conflicts. This provides
conflict-free resolution that preserves changes from both sides.
Key changes:
- Add CRDT merge methods for all entity types (deck, card, note, etc.)
- Update resolve methods to accept optional CRDT binary data
- Fall back to server_wins when CRDT data is unavailable or invalid
- Add comprehensive tests for CRDT conflict resolution scenarios

Add applyCrdtChanges function to process CRDT payloads received from
the server during pull operations. The function merges remote documents
with local ones using Automerge and stores the result in sync state.

Add CRDT document generation to the sync push flow. Each pending entity
is now converted to an Automerge CRDT document and included as base64-
encoded binary in the push payload alongside the existing entity data.

Add comprehensive tests for syncing NoteType, NoteFieldType, Note, and
NoteFieldValue entities in push.test.ts and pull.test.ts. Tests cover:
- Data format conversion between local and server representations
- Applying pulled entities to local IndexedDB
- Pushing pending changes to server
- Updating existing entities during sync
- Syncing all note-related entities together
Also removes unused variable in sync repository.
