SIMD Utf8Transcoder.GetUtf8ByteCount + test suite Introduced SIMD-accelerated Utf8Transcoder.GetUtf8ByteCount for efficient UTF-8 byte counting, replacing all writer-side Encoding.UTF8.GetByteCount usages. Added 29 unit tests for correctness across ASCII, Hungarian, CJK, emoji, and boundary cases. Updated benchmarks to ensure FixStr is bypassed and wire mode is selectable. Documented implementation and dead-code review in BINARY_TODO.md. No public API changes. |
