b669f9f580 feat: add ANSI-aware text measurement and slicing native module
Port Oh My Pi's optimized text utilities to GSD's native engine:
- wrapTextWithAnsi: word-wrap preserving ANSI codes across breaks
- truncateToWidth: truncate with ellipsis options
- sliceWithWidth: column-range extraction
- extractSegments: split around overlay regions
- sanitizeText: strip ANSI, remove control chars, normalize CR
- visibleWidth: display width excluding ANSI sequences

Single-pass ANSI scanning, ASCII fast-path, grapheme-aware Unicode
width measurement, and zero-copy input via UTF-16 JsString interop.

Includes 19 Rust unit tests and 33 Node.js integration tests.
