A telephone-themed bookend set, tuned by ear:
- speak: heartbeat entry ("Speak to Me" woven with warm MF tones), soft-chord
exit (pure sines, easy on the ears on repetition)
- listen: mf-dial start (the genuine Young Lust R1 operator routing sequence,
KP 0-4-4-1-8-3-1 ST) and machine end (Welcome to the Machine throb)
- mf-listen/mf-done gentler alternatives, and a call-waiting blip
listen() is now conversation-first: wait_for_silence defaults on with a 30s
cap, and the "go" tone plays only after the mic is live (warmup) so the first
word isn't clipped. VAD defaults tuned (aggressiveness 3, 2200ms silence,
400ms min-speech) after live testing showed the old values cut replies off on
brief background transients. Adds webrtcvad-wheels for the VAD path.
