StringDecoder correctly assembles multi-byte chars (Cyrillic) across stdin chunk boundaries. Closes Windows Node quirk where Russian prompts were turned into mojibake before sending to Anthropic API (Layer 2 escalation). Stage 3 follow-up fix 1/3 (helper).

/**
|
|
* UTF-8 safe stdin reader for hooks.
|
|
* Fixes Windows Node stdin quirk: default `for await (chunk of stdin)` interprets
|
|
* chunks as Buffer, and `input += chunk` calls .toString() which uses utf-8 BUT
|
|
* fails on chunk boundaries that fall inside multi-byte sequences (e.g. cyrillic
|
|
* 2-byte chars split across chunks).
|
|
*
|
|
* Uses StringDecoder to handle multi-byte chars across chunks correctly.
