Streaming dictation only emits a phrase after phrase_silence_ms of
silence; the 400ms default stalled long continuous speech until the
20s force-split, which read as "the text cuts off". 250ms emits at
short breathing pauses instead.
key_delay_ms was the 2ms default, which drops characters in busy
Node/Ink TUIs like the pi chat while they are streaming output;
10ms keeps dictation readable there.
The default 2s auto-stop ended dictations whenever a thinking pause ran
a little long while the key was still held. 6s keeps room to think
while still bounding a lost-release recording (the guards make missed
releases rare, so the longer bound costs little).
Keep the dictation daemon config versioned with the rest of the setup.
The file carries no secrets (local backend), but if a cloud backend with
an API key is ever configured it must not be committed; whisrs accepts
WHISRS_GROQ_API_KEY-style env vars instead.
