feat(home): interactive 3D forge WebGL hero with real-time forging bursts (Issue #865)

[Tusharkhadde]

Summary

Implements an interactive 3D WebGL forge visualization for the homepage hero that represents bounties being forged in real time.

What’s Included

• Added a new Three.js forge scene component:
  • frontend/src/components/home/ForgeVisualization.tsx
• Integrated the forge visualization into the homepage hero:
  • frontend/src/components/home/HeroSection.tsx
• Added dependencies:
  • three
  • @types/three

Forge Experience

• Real-time forging cycle (periodic forge bursts)
• Particle spark effects using GPU-friendly THREE.Points
• Animated forge elements:
  • molten core pulse
  • hammer strike motion
  • dynamic fire lighting
• Smooth camera motion + subtle orbit behavior
• User interaction:
  • pointer-reactive camera parallax
  • click-to-forge burst trigger
• Performance-oriented rendering setup:
  • requestAnimationFrame loop
  • bounded frame delta
  • pixel ratio clamp
  • resize handling + cleanup/disposal

Acceptance Criteria Mapping

• 3D WebGL scene using Three.js
• Real-time bounty creation visualization
• Particle effects and smooth 60fps-oriented animation loop

Notes

• Hero content/CTAs remain intact; visualization is layered as a non-blocking background.
• Full frontend build currently reports pre-existing unresolved imports (lib/animations, lib/utils) in unrelated files; this PR does not introduce those issues.
