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.
