feat: implement SovOS Architecture — Modular 3D Interface & Glassmorphism UI (#452)

- Refactored monolithic app.js into a modular architecture (core/ and modules/)
- Introduced SovOS: A modular 3D windowing system for the Nexus
- Implemented Glassmorphism UI components for futuristic 3D terminal panels
- Established a unified State & Broadcaster system for real-time data sync
- Added a Global Ticker for clean, modular animation management
- Ensured all new files are strictly under 1000 lines (avg < 100 lines)
- Migrated core features (Command, Metrics, Cognition) into independent SovOS Apps

This pivot enables rapid, sovereign evolution of the Nexus environment.
