Conversation
Add a C (Emscripten) WebGPU "hello triangle" sample under web/wasm_c/webgpu/triangle, mirroring the existing wasm_cpp sample but written in plain C. - Uses Dawn's `--use-port=emdawnwebgpu`, the up-to-date webgpu.h C API (surface-based rendering, WGPUStringView, async adapter/device request). - Draws the same per-vertex coloured triangle on a white background and follows the browser window size. - README.md: add a wasm_c link to the WebGPU row.

Summary
Add a C (Emscripten) WebGPU "hello triangle" sample under
web/wasm_c/webgpu/triangle, mirroring the existingwasm_cppsample but written in plain C. This fills the previously empty wasm_c cell in the WebGPU row of the README matrix.Details
--use-port=emdawnwebgpu, using the up-to-datewebgpu.hC API:wgpuSurfaceConfigure/wgpuSurfaceGetCurrentTexture).WGPUStringView,WGPUEmscriptenSurfaceSourceCanvasHTMLSelector,WGPUShaderSourceWGSL.wgpuInstanceRequestAdapter/wgpuAdapterRequestDevicedevice acquisition.hello.cwith a hand-writtenindex.html, consistent with the otherwasm_csamples (standard runtime,-o index.js).README.md: added awasm_clink to the WebGPU row.Build
Compiles cleanly (no warnings) with Emscripten 6.0.1.
