Pre-release — UX polish
Two fixes on top of the storage work:
- Move library button now hides when every track is already at your chosen folder. Previously tapping it showed "0 tracks moved" with no picker — a confusing dead-end after a successful migration.
- Track count appears in the button ("Move 14 tracks to this folder") so you know exactly what you're about to trigger before tapping.
Supersedes v0.3.4-beta.3. Upgrade to v0.3.4 for the final release.
