Adds a `--timeout <ms>` CLI flag (and `HYPERFRAMES_TRANSCRIBE_TIMEOUT_MS`
env var) plus a model-slowdown factor in the auto-scaled default so
`hyperframes transcribe` doesn't hard-fail with `spawnSync ETIMEDOUT`
on slow CPUs running heavier whisper models.
Field-signal ts=1784165471 (win32/arm64 emulating x64 on Snapdragon,
CLI 0.7.59) reported the failure on a 63s wav with `-m medium` at ~13x
realtime — the historical 10x-realtime scale (PR #2463) gave 10.5 min
while the machine needed ~13.7 min. Splitting audio and merging offsets
was the manual workaround.
- Add `--timeout <ms>` and `HYPERFRAMES_TRANSCRIBE_TIMEOUT_MS` (min 5000).
Explicit override bypasses auto-scaling; still capped at 12h.
- Add per-model slowdown factor (tiny 0.5, base 0.7, small 1, medium 2,
large 4, large-v3-turbo 2). Multiplied into the 10s/audio-second
baseline so medium/large get proportional headroom while `small.en`
(the default) preserves the historical safety window.
- Wrap whisper's spawn error with a discoverability hint naming
`--timeout`, the env var, and the effective timeout when the child
was killed by SIGTERM/ETIMEDOUT (mirrors PR #2504 protocol-timeout).
- Docs: new `--timeout` row in `docs/packages/cli.mdx` Flags table.
Regression coverage in `packages/cli/src/whisper/transcribe.test.ts`
(56 tests) and `packages/cli/src/commands/transcribe.test.ts` (5 tests):
- Model factor per known name + case-insensitive + safe unknown fallback.
- 63s field-signal case on medium.en → 1_260_000ms (was 630_000ms).
- Explicit override honored below the auto floor + capped at 12h.
- Model factor ignored when overrideMs is set.
- SIGTERM/ETIMEDOUT detection + augmented message contract.
- CLI rejects below-minimum `--timeout` with error naming both the flag
and the 5000ms floor.

Add formatSrt/formatVtt/wordsToCues to normalize.ts (the inverse of the
existing parseSrt/parseVtt) and a 'hyperframes transcribe <transcript> --to
srt|vtt' export mode. Word-level whisper transcripts group into cues on
sentence boundaries with maxChars/maxGap guards; imported phrase-level cues
pass through unchanged. Default transcribe behavior is unchanged and no new
dependencies are added.

transcribe hard-failed with cli_error whenever whisper-cpp was absent. On
Linux/Docker/CI (no Homebrew, no compiler toolchain) that is unavoidable, so it
drove ~30k cli_error/day that are really "install the prerequisite" rather than
bugs — and buried genuine transcription failures in the command-error budget.
ensureWhisper now throws a typed WhisperUnavailableError when no binary exists
and none can be built. The transcribe command reports that on a dedicated
transcribe_unavailable metric instead of cli_error, and a new --optional flag
lets pipelines skip captions and exit 0. Real transcription crashes still fail
as cli_error. init and the skill pipelines already continue without captions.
Also removes a stale doc reference to a `transcribe --provider groq` flag that
does not exist.
