Subject: [PATCH] chore(io): Complete migration of pkg/repos to io.Medium

- Migrated pkg/repos/registry.go to use io.Medium abstraction for all file operations.
- Updated all callers in internal/cmd/ to pass io.Local, with proper alias handling.
- Fixed formatting issues in cmd_github.go that caused previous CI failures.
- Added unit tests in pkg/repos/registry_test.go using io.MockMedium.
- Verified project-wide build and new unit tests pass.
