/// Fully decodes and encodes all 8 BC7 modes (0–7) according to the
/// BC7/BPTC specification.  No external dependencies – pure C++20.
///
/// Implementation is split into .inl parts under bc7/ for readability:
///   decode.inl         – mode table, block decoder, decodeTexture
///   encode_common.inl  – colour helpers, PCA, endpoint fitting
///   encode_mode[0-7].inl – individual mode encoders
///   encode_block.inl   – partition search, encode_block dispatch, encodeTexture
