Add -sUSE_WEBGL2=1 -sMIN_WEBGL_VERSION=2 -sMAX_WEBGL_VERSION=2 to both
EMCC_CFLAGS and linker flags. raylib 5.x enables VAOs by default which
require WebGL2; without it glVertexAttribPointer fails on the clientside
property of an undefined VAO object.

- Cargo.toml: gate `wayland` feature behind cfg(not(wasm32)) so the
dependency resolves correctly for both native and web targets
- .cargo/config.toml: WASM linker flags (ASYNCIFY, GLFW, memory growth)
- build_web.sh: sets required EMCC_CFLAGS, builds, copies artefacts to web/;
accepts --serve to start a local HTTP server
- web/index.html: minimal Emscripten shell with canvas and status line
- .gitignore: exclude generated web/*.js and web/*.wasm artefacts
- README: document web build prerequisites and usage
ASYNCIFY lets the native while-loop main loop run unchanged in the browser.
Build output: ~267 KB JS + ~458 KB WASM.
