Implement device registration and save sync tracking to enable multi-device save management with conflict detection. - Device CRUD endpoints (POST/GET/PUT/DELETE /api/devices) - Save sync state tracking per device - Conflict detection on upload (409 when device has stale sync) - Download sync tracking (optimistic and confirmed modes) - Track/untrack saves per device - DEVICES_READ/WRITE scopes for authorization
