fix(cms): replace symlinks with rsync copy; drop stale zod v3 override

src/ and scripts/ were symlinked into the Astro project root pointing
into the nullfs-mounted bootstrap dir. Vite resolves symlink targets and
then can't find node_modules at the mount path, breaking builds. Switch
to rsync -a --delete so the working copy is always a real directory.

Remove the zod 3.25.76 override from package.json and setup/cms.ts —
it was a v3/v4 conflict workaround that no longer applies and was
breaking fresh npm installs.
