0.2.0

What's new

• Per-stem pan knobs: Pan each stem left or right (drag or arrow keys, double-click to center). Pan is saved per song and survives seek, restart, and song switching.
• Keyboard mute: Number keys 1–6 mute each stem lane, top to bottom. Space still toggles play.
• Skip controls: 5s skip back/forward buttons around the play button — hold (or press) Shift for 15s. Arrow keys seek too (Shift for 15s).
• Data folder override: Set STEMKIT_DATA_DIR=/path/to/folder to move the app's data (venv, models, songs, library) anywhere you want.
• About StemKit: New About screen with app version, quick links, and a "Check for updates" button.

Fixes

• Auto-update and help links point to the correct repository, so update checking works reliably for existing installs.
