    nanobsd: Offset code partition to a track boundary
    
    Ensure the primary and secondary code partitions start at a proper track
    boundary by applying a NANO_SECTS offset in bytes.
    
    While track-boundary alignment is largely obsolete on modern storage,
    this change maintains compatibility with current images (legacy).  A
    future commit will transition to 1 MiB alignment boundaries.
