Browser + Hardware Feature Probe v0.1.0

Single-file diagnostic for: Canvas (HTML Canvas), WebGL (Web Graphics Library) 1 and 2, WebGPU (Web Graphics Processing Unit), WebAssembly (Wasm), threading prerequisites (SharedArrayBuffer + Atomics + cross-origin isolation), and practical engine-facing limits.
Tip: For multithreading in WebAssembly (Wasm) via pthreads (Portable Operating System Interface threads), you must have cross-origin isolation enabled (Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy headers).
