Visual polish pass (v0.2.0): phase lighting, street lamps, marquee, dressing, night screenshots

- Phase-based lighting: sun direction/energy/color, ProceduralSkyMaterial
  gradient, and ambient per shift phase (GameManager.PHASE_LIGHTING),
  applied on phase transitions and shift start
- WorldBuilder: street lamp poles with emissive bulbs + OmniLights,
  set_night_mode(), glowing STEP LINE marquee (Label3D + emissive bars),
  crosswalk stripes, planters, low-poly street trees
- NPC avatars: per-seed height/brightness variation (deterministic LCG)
- Denser routine traffic probabilities
- capture_screenshots.gd: fast-forward to LATE phase and capture night set;
  README gallery is now 2x3 day+night; docs/screenshots regenerated
- Version bumped to 0.2.0; build/ artifacts rebuilt; Linux binary smoke-tested
- New headless tests for phased lighting config and street dressing (56 total)

 - Simulation extras: protester archetype, CALL_SOMEONE reaction, door lock/secure mechanic (visual indicator), flashlight with night perception bonus, LATE shift phase reaching the violent-threat event
