Allegro d9cf77e382 feat: Issue #42 - Nexus Architect for autonomous Three.js world building 
Implement Phase 31: Autonomous 'Nexus' Expansion & Architecture

DELIVERABLES:
- agent/nexus_architect.py: AI agent for natural language to Three.js conversion
  * Prompt engineering for LLM-driven immersive environment generation
  * Mental state integration for dynamic aesthetic tuning
  * Mood preset system (contemplative, energetic, mysterious, etc.)
  * Room and portal design generation

- tools/nexus_build_tool.py: Build tool interface with functions:
  * create_room(name, description, style) - Generate room modules
  * create_portal(from_room, to_room, style) - Generate portal connections
  * add_lighting(room, type, color, intensity) - Add Three.js lighting
  * add_geometry(room, shape, position, material) - Add 3D objects
  * generate_scene_from_mood(mood_description) - Mood-based generation
  * deploy_nexus_module(module_code, test=True) - Deploy and test

- agent/nexus_deployment.py: Real-time deployment system
  * Hot-reload Three.js modules without page refresh
  * Validation (syntax check, Three.js API compliance)
  * Rollback on error with version history
  * Module versioning and status tracking

- config/nexus-templates/: Template library
  * base_room.js - Base room template (Three.js r128+)
  * portal_template.js - Portal template (circular, rectangular, stargate)
  * lighting_presets.json - Warm, cool, dramatic, serene, crystalline presets
  * material_presets.json - 15 material presets including Timmy's gold, Allegro blue

- tests/test_nexus_architect.py: Comprehensive test coverage
  * Unit tests for all components
  * Integration tests for full workflow
  * Template file validation

DESIGN PRINCIPLES:
- Modular architecture (each room = separate JS module)
- Valid Three.js code (r128+ compatible)
- Hot-reloadable (no page refresh needed)
- Mental state integration (SOUL.md values influence aesthetic)

NEXUS AESTHETIC GUIDELINES:
- Timmy's color: warm gold (#D4AF37)
- Allegro's color: motion blue (#4A90E2)
- Sovereignty theme: crystalline structures, clean lines
- Service theme: open spaces, welcoming lighting
- Default mood: contemplative, expansive, hopeful
