9e0dc8b472- copyBytesFrom: calculate byte offsets directly instead of
slicing into an intermediate typed array
- toString('hex'): use V8 Uint8Array.prototype.toHex() builtin
- fill: add single-char ASCII fast path
- indexOf: use indexOfString directly for ASCII encoding
- swap16/32/64: add V8 Fast API functions
