Fix rollback dropping hidden cache records

Pass shadowed_registry: true to cargo_copies_still_patched in rollback
to detect patched copies in the shared /usr/local/cargo/registry/src even
when shadowed by a vendor directory. This prevents dropping manifest
records for still-patched cache copies, matching scan prune's behavior.

Fixes bug where rollback with vendor/ present would skip cache-patched
crates, succeed on vendored copies, then drop the manifest record,
orphaning the patched cache copy with no way to restore it.
