Adds a Server/Browser toggle to the playground. In Browser mode, code runs entirely client-side through the Hemlock interpreter compiled to WebAssembly (no Grove server, no network round-trip). - playground.html: execution-mode toggle (persisted in localStorage), lazy load + init of the WASM interpreter, stdout/stderr capture, and graceful fallback when artifacts are missing. Check/Format/stdin (server-backed) are disabled in Browser mode. Supports a ?wasm=URL override for CDN hosting. - wasm/: vendored JS wrapper (hemlock-api.js, pre.js) plus the generated interpreter artifacts (hemlock.js, hemlock.wasm) built from hemlang/hemlock. - build-wasm.sh: regenerates the artifacts via 'make wasm-interpreter'. - grove.hml: serve /wasm/* static assets, streaming the binary .wasm byte-for-byte so it isn't corrupted by string concatenation. - Docs: README, wasm/README, and CLAUDE.md updated. Frontend verified end-to-end in a headless browser (run, error output, mode persistence, toggle re-enabling server controls).
