docs(voice-packs): runbook, index link, and the log entry

The page a new operator needs: what the three required files are and who
reads each one, how a pack is built (with the extractor's usage text
verbatim, because the flags are not guessable and there is no -o), the
10-second gate and where it fires twice, how to add a fourth voice
including the warm hook that registers a pack without restarting the
engine, and the engine-bump procedure for when the artifact sizes move.
Plus the host census as of 2026-10-18 — the trial packs carry no
artifacts and their manifest is the trial's own schema, so the builder's
first real run is a --force migration — and the three gaps left open on
purpose: no curated ICL transcript, no 16 kHz variant, no loudness pass.
