Subject: [PATCH] fix: track hook files in manifest for local patch detection
 (#769)

Hook files (gsd-statusline.js, gsd-check-update.js, gsd-context-monitor.js)
are installed during updates but were never included in gsd-file-manifest.json.
This means saveLocalPatches() could not detect user modifications to hooks,
causing them to be silently overwritten on update with no backup.

Add hooks/gsd-*.js to writeManifest() so the existing local patch detection
system automatically backs up modified hooks to gsd-local-patches/ before
overwriting, matching the behavior already in place for workflows, commands,
and agents.
