Plan for Adding WebAssembly (WASM) Support to the Web Builder Framework

     1. Create WASM Optimizer Module (framework/optimizers/optimize-wasm.nu)

     - Build WASM modules using external tools (wasm-pack, wasm-bindgen-cli, emscripten)
     - Support for Rust, C/C++, AssemblyScript, and Go compilation
     - Optimize WASM binaries with wasm-opt
     - Generate JavaScript glue code and TypeScript definitions
     - Handle WASM instantiation patterns (sync/async)

     2. Extend Configuration System

     - Add [wasm] section to page.config.toml template
     - Configure WASM source files and build commands
     - Specify target environments (web, node, bundler)
     - Set optimization levels and features
     - Define memory limits and threading options

     3. Update Build Pipeline (framework/core/build.nu)

     - Add WASM compilation step parallel to JS/CSS processing
     - Copy WASM binaries to dist directory
     - Generate loader scripts for WASM modules
     - Handle WebAssembly.instantiateStreaming fallback
     - Support WASM module dependencies

     4. Add WASM Development Support (framework/core/dev.nu)

     - Watch WASM source files for changes
     - Hot-reload WASM modules during development
     - Provide WASM debugging information
     - Support source maps for WASM

     5. Create WASM Tool Integration (framework/core/framework-utils.nu)

     - Detect installed WASM toolchains
     - Validate WASM build requirements
     - Provide fallback mechanisms
     - Support multiple WASM languages

     6. Add WASM-specific Templates

     - Create page templates with WASM integration
     - Provide example Rust/C++ WASM projects
     - Include WebAssembly loader utilities
     - Add performance measurement tools

     Configuration Example:

     [wasm]
     enabled = true
     source_dir = "src/wasm"
     output_dir = "dist/wasm"
     modules = [
         { name = "compute", source = "src/lib.rs", lang = "rust" },
         { name = "graphics", source = "main.c", lang = "c" }
     ]

     [wasm.rust]
     toolchain = "wasm-pack"  # or "cargo-web"
     target = "web"  # web, nodejs, bundler
     optimization = "O3"
     features = ["simd", "threads"]

     [wasm.optimization]
     use_wasm_opt = true
     opt_level = 3  # 0-4
     shrink_level = 2  # 0-2

     Key Benefits:

     - Performance: Native-speed computation for heavy tasks
     - Language flexibility: Use Rust, C++, Go, or AssemblyScript
     - Progressive enhancement: WASM as optional optimization
     - Development experience: Hot-reload and debugging support
     - Production ready: Optimization and compression built-in

     This approach integrates WASM as a first-class citizen in the framework while maintaining the existing architecture and workflow.
