When a user manually installs a dev branch where VERSION > npm latest,
gsd-check-update detects hooks as "stale" and the statusline showed
the red "⚠ stale hooks — run /gsd-update" message. Running /gsd-update
would incorrectly downgrade the dev install to the npm release.
Fix: detect dev install (cache.installed > cache.latest) in the
statusline and show an amber "⚠ dev install — re-run installer to sync
hooks" message instead, with /gsd-update reserved for normal upgrades.
Also expand the update.md workflow's installed > latest branch to
explain the situation and give the correct remediation command
(node bin/install.js --global --claude, not /gsd-update).
