Subject: [PATCH] refactor(@angular/cli): exclude Cnpm from LOCKFILE_NAMES type

The `LOCKFILE_NAMES` constant in `packages/angular/cli/src/utilities/package-manager.ts` is updated to explicitly exclude `PackageManager.Cnpm` from its type definition. This refactors the type to accurately reflect the package managers supported by the lockfile detection logic.
