leafyy 05ac66edfa fix(stage-tamagotchi): show Live2D expressions in settings (#2451) ...

## Summary

- Send a serializable Live2D expression snapshot from the stage renderer
to the separate Settings window.
- Route expression changes back to the renderer that owns the loaded
model, with owner ID checks for stale-window isolation.
- Add browser regressions for the component boundary and the complete
BroadcastChannel round trip.

Fixes #2450
