…sort - Add Rust crate (rust/) with searchsorted and natsort implementations - searchsorted_f64, searchsorted_many_f64, argsort_f64 (float64, NaN-last) - searchsorted_str, searchsorted_many_str, argsort_str (lexicographic) - nat_compare, nat_sorted, nat_argsort (natural sort with ignoreCase/reverse) - 15 Rust unit tests all passing - Build WASM via wasm-pack --target nodejs to rust/pkg/ - Add TypeScript glue layer (src/wasm/) - types.ts: TsbWasmModule interface (authoritative API contract) - loader.ts: lazy WASM loader via createRequire; isTsbWasmModule type guard - accelerated.ts: public wrappers with TS fallbacks for all 6 functions - index.ts: public module index - Add wasm-coverage.json: 121-entry manifest (6 rust-wasm, 115 ts-only-ineligible, 0 unclassified, 0 eligible_missing) - Add tests/wasm/parity.test.ts: 35 parity tests (all pass) - Add benchmarks/wasm-core/run.ts + results-wasm-core.json - Add scripts/wasm-coverage-check.ts: manifest validator - Add package.json scripts: wasm:build, wasm:test, wasm:coverage, bench:wasm-core - Update biome.json to ignore rust/ and scripts/ directories Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
