Function build_file_change_summary

atomic-agent/src/record/message.rs:289–334

Build a human-readable summary of file changes from the repository status. Groups changes by kind and lists filenames (not full paths) to keep the message concise. Examples: - `"Add src/main.rs, Cargo.toml"` - `"Modify auth.rs; delete old_config.toml"` - `"Add 12 files"` - `"Modify handler.rs; add 5 files"`

    status: &RepositoryStatus,
    untracked_paths: &[String],
