v3.0.1

Fixed

• journal models pull now actually provisions the model journal log
  needs. The pull command's transcriber slot downloads a faster-whisper
  (CTranslate2) model for the WhisperX meeting pipeline — an artifact the
  whisper.cpp backend behind journal log <audio.wav> cannot read — yet every
  missing-model error and doctor hint said "run journal models pull", which
  succeeded while fixing nothing. A new log_transcriber pull slot (config
  log.transcriber.{model_id,revision,checksum}, default
  ggerganov/whisper.cpp) fetches the ggml artifact (ggml-<model>.bin), and
  model resolution — shared by journal log, its record-start preflight, and
  journal doctor — now checks the manual-install path
  (<model_dir>/<model>.bin, which always wins) and the pulled layout.
  models list/verify/MODELS.md cover the log model too. Set
  log.transcriber.model_id: "" to keep manual installs authoritative.
• journal doctor no longer reports failed optional checks as [ok ].
  v3.0.0's audio-toolchain checks (and the older reranker/Quill informational
  checks) printed failure text — "whisper.cpp binary not found", "model missing
  — run journal models pull" — under an [ok ] mark and still concluded
  "all checks passed". Optional-but-broken checks now render as [warn], the
  summary reads "all required checks passed — N warning(s) above", and the
  --json report gains a per-check warn field (additive; ok semantics and
  the exit code are unchanged — warnings still never fail doctor).
