Add `byteAt(index)`, `codePointAt(index)`, and `bytes` sequence to String, enabling direct byte-level manipulation of UTF-8 encoded strings. Introduce `\x` hex escape sequence in string literals for specifying raw byte values. Refactor Unicode escape parsing into a generic `readHexEscape` function supporting variable digit counts. Implement `wrenUtf8Decode` utility for decoding UTF-8 sequences from byte buffers. Add comprehensive tests for `byteAt` including boundary conditions and error cases.
