Implement a day/night cycle following real UTC time. Sunrise/sunset lighting transitions. Agents glow brighter at night. Stars appear. Use Three.js directional lights.

Summary of changes:

  • New js/daynight.js: computes sun elevation from real UTC time, drives a THREE.DirectionalLight sun arc (east → overhead → west), adjusts ambient color, fog, and star visibility each frame via smoothstep transitions
  • Sunrise ~06:00 UTC, sunset ~18:00 UTC. Sun color: warm orange at horizon, muted matrix-green at zenith
  • Existing starfield fades during day, glows green at night (opacity 0.05–0.85)
  • Agent emissive intensity and point-light strength both boosted at night via nightFactor passed to updateAgents()
  • WebGL context-loss safe: refs disposed in disposeWorld/disposeEffects, re-initialised on rebuild
  • vite build passes clean
