Genesis Self-Improvement Loop
==============================
Autonomous capability assessment and improvement system.

Based on 2025 research:
- ALAS Pipeline: Autonomous curriculum generation
- Memory-R1: RL-based memory management
- R-Zero: Co-evolutionary Challenger/Solver pattern
- Absolute Zero Reasoner: Self-directed learning through curiosity

Implements continuous self-improvement:
1. ASSESS - Evaluate current capabilities
2. IDENTIFY - Find improvement opportunities
3. PLAN - Design enhancement strategy
4. EXECUTE - Implement improvements
5. EVALUATE - Measure outcomes
6. LEARN - Update knowledge base
