feat: terminal-run only — drop systemd/autostart, start does mic-check + visible loop

terminal-run is the product, so remove all backgrounding: delete the
claudedo.service unit and autostart.sh, strip the systemd step and the
autostart source-line from install.sh (rc block now sources cc.sh only).

claudedo start now runs a mic check first (warm-up + brief capture, aborts with
guidance if silent; --skip-audio-check to bypass) then drops into a visible
listen loop printing the recognition/action log: a startup banner, then
heard -> matched -> target / injected per utterance, target/mode state changes,
and (listen mode) non-wake speech dropped WITHOUT the transcript per the privacy
invariant.
