Module normalizer 

Single-pass SIMD-guided normalizer implementations (NFC, NFD, NFKC, NFKD).

The core loop scans 64-byte chunks via SIMD to identify passthrough regions (all bytes below a form-dependent bound), copying them directly. Non-passthrough bytes trigger scalar decode + decompose + CCC sort + optional recomposition.
