They'd already drifted apart in wording after a recent edit only landed
in one of them, and docs/deployment.md wasn't linked from anywhere
(index.md's marketing rewrite dropped the old doc-links list) --
orphaned and duplicate. Replace it with a short pointer to
DEPLOYMENT.md on GitHub as the single source of truth, matching the
index.md "full docs live in the repo" pattern.
