Recognize simple device commands in the transcript and act on them without
a Tatlock round-trip. commands.match() maps volume up/down, mute/unmute,
"set volume to N", and "goes to eleven"/max to a "command" message sent
straight to the device; the utterance never reaches the LLM. Matching is
deliberately precise so real requests ("set an alarm for a quarter to
eleven") are not hijacked. Adds the "command" message to the device
protocol in docs/architecture.md.
