Prevent processing of muted user's speech after unmuting on WebGL

uezo · uezo · commit 50700b672a00 · 2025-04-27T17:13:14.000+09:00
- Fixed a bug where speech data from a muted user could be processed after unmuting in WebGL builds.
- Now, when the user is muted or the microphone is not recording, the buffer is cleared and no old audio data is processed after unmuting.
- This prevents unintended speech recognition or processing of buffered audio that was captured during mute state.
