VTuber AI Assistant v0.2.7 Update

patch notes for v0.2.7, use this:> - **Fixed:** VRM model upload now works correctly — models save and persist properly across app restarts. Previously some players (especially on packaged/Steam builds) saw an error when uploading a custom VRM.
> - **Fixed:** Uploading many VRM files no longer slows down or fails.
> - **Added:** ↻ **Recenter Button** — a small floating button that snaps your VRM model back to center. Single-click to recenter, double-click to hide (useful while recording/streaming), hover over the hidden position to reveal it again.
