- Added native text utilities in pi-natives (visible width, truncation, slicing, segment extraction) - Wired pi-tui to use native implementations with short-string JS fast path - Optimized key matching via cached parsed key ids - Refactored visual truncation to reuse Text instances - Reduced theme color lookups by switching from Map to plain records - Regenerated WASM artifacts Benchmarks (after vs before, lower is better): - truncateToWidth/ansi: 20.37ms vs 38.13ms (2000 iters) - sliceWithWidth/ansi: 5.12ms vs 20.39ms - extractSegments/ansi: 8.92ms vs 27.60ms - truncateToVisualLines: 3.51ms vs 411.55ms (500 iters) - visibleWidth/ansi: 0.24ms vs 0.31ms
