// mcpp.lockfile — backward-compat shim. The implementation has moved
// to `mcpp.pm.lock_io` as part of the package-management subsystem
// refactor (PR-R2 in
// `.agents/docs/2026-05-08-pm-subsystem-architecture.md`).
//
// All existing callers continue to use `mcpp::lockfile::Lockfile`,
// `mcpp::lockfile::load`, etc. — the aliases below resolve those to
// the new `mcpp::pm` types. Once `cli.cppm` migrates to `mcpp::pm::`
// directly this shim can be deleted.
