    The real M3 grammar lives in the Rust tool-parser crate. This class only

    M3 is not M2 with renamed tags: it prefixes each structural tag with the
    MiniMax namespace marker, allows multiple ``<invoke>`` tags in one wrapper,
    and represents nested arguments with parameter-name XML tags.
