  2. perf(decode): use TextDecoder with ASCII fast-path for string decoding 

    Replace Buffer.toString('utf8') with TextDecoder for string decoding,
which is faster in modern Node.js. Add ASCII fast-path for short strings
(<32 bytes) common in map keys, avoiding TextDecoder overhead.

- Move string decoding logic from byte-utils.js to 3string.js
- Remove unused toString, utf8Slice, UTF8_THRESHOLD from byte-utils.js

Benchmark results (decode):
- Bluesky(ish) posts: +29%
- Strings (medium/long): +44-66%
- Strings (short): +19%
- Nesting depth: +15-27%
- Maps: +4-9%

Minor behavioural change with this is that we now strip UTF-8 BOM
(U+FEFF) from the beginning of strings when decoding. Rather than
treat this as breakage, I'm saying this is a bug fix (it's
meaningless in UTF-8 and discouraged by Unicode).
