Only show the hardware acceleration tip when acceleration is off

[Yoosseph]

Closes #23

What changed

• Added lib/graphics-acceleration.ts, which detects whether the browser renders WebGL on the GPU:
  • creates a WebGL context with failIfMajorPerformanceCaveat: true
  • reads the renderer name (WEBGL_debug_renderer_info) and flags software renderers (SwiftShader, llvmpipe, Microsoft Basic Render Driver, WARP, ...)
• The performance tip is now hidden only when acceleration is confirmed on. Anything uncertain still shows it, because an unneeded reminder is harmless but a missed one leaves the viewer slow.
• Added tests/graphics-acceleration.test.ts covering the renderer classifier and the decision logic.

Testing

• npm run check, npm run lint, npm test
• Manual: turn off "Use graphics acceleration when available" in Chrome, relaunch, and the tip appears; turn it back on and the tip no longer appears.
