Fixes #4

What this does

New js/daynight.js module drives the entire day/night system from real UTC time
A DirectionalLight sun arcs east→overhead→west: sunrise ~06:00 UTC, sunset ~18:00 UTC
Sun color transitions: warm orange near horizon, muted matrix-green at zenith
Ambient light brightens/shifts cyan during day, dims to dark green at night
Fog color subtly brightens at day, stays black at night
Existing starfield opacity driven by night factor (invisible at noon, bright at midnight)
Agent emissive glow and per-agent point-light intensity boost at night
Smooth transitions via smoothstep around the dawn/dusk horizon crossing
WebGL context-loss recovery: all refs disposed and re-initialised cleanly
Build verified: vite build passes with no errors

Fixes #4 ## What this does - New `js/daynight.js` module drives the entire day/night system from real UTC time - A `DirectionalLight` sun arcs east→overhead→west: sunrise ~06:00 UTC, sunset ~18:00 UTC - Sun color transitions: warm orange near horizon, muted matrix-green at zenith - Ambient light brightens/shifts cyan during day, dims to dark green at night - Fog color subtly brightens at day, stays black at night - Existing starfield opacity driven by night factor (invisible at noon, bright at midnight) - Agent emissive glow and per-agent point-light intensity boost at night - Smooth transitions via `smoothstep` around the dawn/dusk horizon crossing - WebGL context-loss recovery: all refs disposed and re-initialised cleanly - Build verified: `vite build` passes with no errors

feat: add day/night cycle driven by real UTC time 87486d2c7f

- 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.

Fixes #4
