 - Added `RimeHttpTTSService` and the `07q-interruptible-rime.py` foundational
   example.
+- Added `STTMuteProcessor`, a general-purpose processor that combines STT
+  muting and interruption control. When active, it prevents both transcription
+  and interruptions during bot speech. The processor supports multiple
+  strategies: `NEVER` (default), `FIRST_SPEECH` (mute only during bot's first
+  speech), `ALWAYS` (mute during all bot speech), or `CUSTOM` (using provided
+  callback).
+- Added STTMuteFrame, a control frame that enables/disables speech
+  transcription in STT services.
