Slugs are not globally unique (mesh.id is canonical) so the route
only validates the regex and updates the row. CLI refuses a local
collision (two joined meshes sharing a slug would make the picker
ambiguous) and rewrites ~/.claudemesh/config.json on success.
Other peers pick up the new slug on next claudemesh sync.
Server: PATCH /api/cli/meshes/:slug body now accepts { name?, slug? }
— same route, just optional both fields.
