Adds the transport-independent core of the MaSzyna Hardware Protocol v2: COBS framing with a CRC32C protected 24 byte header, bounds checked payload readers and writers, and a resynchronising stream decoder. The shared TrainState registry describes simulator state in engineering units with per-value quality, the command registry generates the command namespace from Commands_descriptions, and the symbol registry merges both into the public, name-addressed hardware api.
