feat: start skips the mic check by default; --check to opt in

invert the pre-listen mic check — default is no check (just start listening); pass
'claudedo start --check' to run it. replaces the old --skip-audio-check flag.

-- **`auto_target`** (default `false`): with no sticky target set and exactly one

-- **`print_heard`** (default `false`, debug): prints non-wake transcripts to the
-  console so you can see how Whisper renders your wake word. Turn it on to debug
-  detection, then off. Whisper has no token for "claudedo" — it commonly emits
-  "claude do" or "claude due", both of which are in the default wake list.
+- **STT biasing.** The transcriber is seeded with an `initial_prompt` built from the
+  configured wake phrases + command vocabulary (one source — `grammar.vocabulary()`),
+  so Whisper is conditioned to expect "claudedo" and the command words.
+- **Split fuzzy thresholds.** `wake_fuzzy_threshold` (default `0.6`, lenient) vs
+  `command_fuzzy_threshold` (default `0.8`, tight). The asymmetry is deliberate: a
+  false *wake* is cheap (it wakes, finds no command, does nothing), but a false
+  *command* fires the wrong action. Prefer expanding command synonyms over loosening
+  the command threshold.
+- **`[vad]` endpointing.** Capture starts on speech and ends after `silence_ms`
+  (default 800) of trailing silence — Alexa-style record-until-pause — capped at
+  `max_seconds` (default 10). The pause both ends a command and separates it from
+  following chatter (the chatter is a separate capture the wake gate discards).
+- **`auto_target`** (default `false`): with no sticky target and one session running,
+  `false` does nothing and asks you to `set`; `true` auto-uses that session.
