The #330 migration that renames `statusline.js` → `gsd-statusline.js`
uses `.includes('statusline.js')` which matches ANY file containing
that substring. For example, a user's custom `ted-statusline.js` gets
silently rewritten to `ted-gsd-statusline.js` (which doesn't exist).
This happens inside `cleanupOrphanedHooks()` which runs before the
interactive "Keep existing / Replace" prompt, so even choosing "Keep
existing" doesn't prevent the damage.
Fix: narrow the regex to only match the specific old GSD path pattern
`hooks/statusline.js` (or `hooks\statusline.js` on Windows).
