Introduce a new webui-wasm crate that compiles the full WebUI parse → protocol → render pipeline to WebAssembly, enabling an interactive browser-based playground with zero server dependencies. WebAssembly crate (crates/webui-wasm): - Exposes build_and_render(), build_protocol(), and render() via wasm-bindgen for JavaScript consumption - Uses the real webui-parser with CssStrategy::Inline so component styles work in-memory without external CSS files - Feature-gates walkdir/filesystem behind 'fs' feature so webui-parser compiles cleanly for wasm32-unknown-unknown - Removes 6 unused deps from webui-parser (tokio, anyhow, tree-sitter-typescript, lazy_static, nom, streaming-iterator) - Bumps tree-sitter-language to 0.1.7 for bundled WASM C headers Build tooling: - Cross-platform cargo xtask build-wasm command with auto-detection of LLVM clang, wasi-libc, and WASM headers per OS - Friendly colored error messages with platform-specific install hints using the console crate (matches webui-cli style) - JS glue patching to replace tree-sitter env imports with inline C stdlib stubs for browser compatibility - Reusable GitHub Actions composite action (.github/actions/setup-wasm) shared by PR checks and docs deployment workflows - Refactored xtask into modules: main.rs, build_wasm.rs, build_apps.rs, util.rs

Remove the label-based gate that required a 'wasm' label on the PR for the WASM build job to run. The job now runs unconditionally on every PR, matching the CI job behavior. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

The webui-protocol crate needs protoc for prost-build. Add protobuf-compiler to the apt-get install in the composite action. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
tree-sitter-html's scanner.c uses strncpy and towupper which are not in tree-sitter-language's minimal WASM header stubs. Install the wasi-libc package (available on Ubuntu 24.04) to provide the complete C stdlib headers needed for WASM compilation. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
The wasi-libc apt package installs headers to /usr/include/wasm32-wasi (not /usr/share/wasi-sysroot/include/wasm32-wasi). Update both the CI action and xtask detection to check this path first. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Ubuntu's system clang already supports --target=wasm32-unknown-unknown. tree-sitter-language 0.1.7 ships bundled WASM C headers (via cargo fetch). Add -Wno-implicit-function-declaration for missing strncpy/towupper declarations in the minimal stubs — these link fine from wasm stubs. Removes: clang, llvm, lld, wasi-libc apt packages from CI. Keeps: protobuf-compiler (for prost-build) and wasm-pack. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Does it require the README change on how to play with wasm? |
