TTS feedback loop (hermes_cli/voice.py)
The VAD loop kept the microphone live while speak_text played the
agent's reply over the speakers, so the reply itself was picked up,
transcribed, and submitted — the agent then replied to its own echo
("Ha, looks like we're in a loop").
Ported cli.py:_voice_tts_done synchronisation:
- _tts_playing: threading.Event (initially set = "not playing").
- speak_text cancels the active recorder before opening the speakers,
clears _tts_playing, and on exit waits 300 ms before re-starting the
recorder — long enough for the OS audio device to settle so afplay
and sounddevice don't race for it.
- _continuous_on_silence now waits on _tts_playing (up to 60 s) before
re-arming the mic with another 300 ms gap, mirroring
cli.py:10619-10621. If the user flips voice off during the wait the
loop exits cleanly instead of fighting for the device.
Without both halves the loop races: if the silence callback fires
before TTS starts it re-arms immediately; if TTS is already playing
the pause-and-resume path catches it.
Red REC badge (ui-tui appChrome + useMainApp)
Classic CLI (cli.py:_get_voice_status_fragments) renders "● REC" in
red and "◉ STT" in amber. TUI was showing a dim "REC" with no dot,
making it hard to spot at a glance. voiceLabel now emits the same
glyphs and appChrome colours them via t.color.error / t.color.warn,
falling back to dim for the idle label.
