    repo: add paths.toplevel to repo info
    
    repo info currently does not expose the repository's working tree root,
    even though this information is available via repo_get_work_tree().
    
    This makes it harder for scripts to retrieve the repository root through
    a structured interface, often requiring the use of git rev-parse
    --show-toplevel.
    
    Add a new field paths.toplevel to git repo info that returns the working
    tree root. For bare repositories, this value is empty, consistent with
    other non-applicable fields.
    
    This provides a consistent and script-friendly way to query repository
    paths without invoking additional commands.
