Alexander Whitestone ec6dc0aa01 feat: add lens flare effect for bright light sources (#109) ...

Implement Three.js scene with procedural lens flare using CanvasTexture:
- Build radial glow, star-burst streak, ring, dot, and hex aperture
  textures from canvas draws — no image assets required
- Attach Lensflare + LensflareElement chain to the sun PointLight;
  Three.js handles screen-space projection and occlusion automatically
- Sun arcs slowly across sky, so flare angle and ghost positions shift
  over time giving a live optical effect
- Add starfield (4 000 points), grid floor, and portal rings loaded
  from portals.json to give the flare context in a real 3D scene
- Wire audio toggle, chat panel, and WebSocket events

Fixes #109
