Brooklyn Nicholson edb12bf423 fix(voice): stop wake re-fire loop and empty-transcript error spam
Two bugs surfaced by the desktop wake conversation:

1. Runaway loop: wake -> voice -> resume -> wake fired again within
   ~200ms. openWakeWord keeps its rolling feature buffer across
   pause/resume, so on resume it immediately re-scored the "hey jarvis"
   captured before the pause and re-fired, reopening a session and
   restarting voice in a tight cycle. Reset the engine buffer on every
   detector (re)start so resume begins from clean audio.

2. Empty-transcript toast: a silent re-listen returns
   success:false / "… STT returned empty transcript", which the desktop
   transcribe endpoint turned into a 400 -> thrown error -> "Voice
   transcription failed" notification on every silent gap. Treat an empty
   transcript as no-speech: return {ok, transcript: ""} so the voice loop
   quietly re-listens. Real failures still 4xx/5xx.
