If this variable is NULL, setup_standard_excludes() in dir.c forcefully evaluates and assigns the XDG default path to it. Continue the libification effort by encapsulating this lazy-loading fallback logic into a proper getter and moving the variable into 'struct repo_config_values'. Since 'excludes_file' is a dynamically allocated string, it requires proper heap memory management. Introduce repo_config_values_clear() and wire it up in repo_clear() to safely free this memory when a repository instance is destroyed. Also clean up the heap-allocated 'attributes_file' in this new destructor while we are at it. Note: 'if (!repo->initialized)' is added in both the getter and the destructor. This ensures we safely return or bypass cleaning up uninitialized repositories without hardcoding a dependency on 'the_repository'.
