Release v0.7.0

Playback

• Per-library saved queues: each collection (Audiobooks / Podcasts / Music) keeps its own queue with shuffle order and position. The Resume chip on a library screen restores exactly that library; switching libraries preserves both queues, across app restarts.
• Fixed Bluetooth media controls: play/pause from earbuds now works reliably, including right after process death (media buttons no longer swallowed; framework queue resumption restored).
• Rewind / fast-forward buttons honor the seek increments configured in app settings.

Internal

• Wired (USB) watch deploy/test support and hardened port discovery for the k8s tooling.
