docs(cloud-replay): fix CI (prettier + Vale) and review nits

- Run prettier --write on cloud-replay.md (fixes the prettier check).
- Vale: whitelist legit technical terms (overridable, libpq, cbshim, stdin,
  sudo) in the Base accept vocab, and de-hyphenate "freshly changed"
  (Google.LyHyphens).
- Address Copilot review: "Two axes" → "Three axes" (a third auth axis was
  added); drop the non-existent `-v` alias (docs use `--debug`); clarify
  that only the three overlay branch flags are mutually exclusive and
  `--branch` is the separate legacy CI-derived name.
