- New js/daynight.js module: computes sun elevation from UTC time,
drives a DirectionalLight sun arc (east → zenith → west), adjusts
ambient color/intensity, fog color, and star opacity each frame.
- Sunrise ~06:00 UTC, sunset ~18:00 UTC with smooth transitions.
- Stars (existing starfield) fade during day and glow green at night.
- Agent emissive glow and point-light intensity boost at night via
nightFactor passed to updateAgents().
- WebGL context-loss recovery: daynight refs disposed in disposeWorld /
disposeEffects and re-initialised on rebuild.
