consciousness_experiments 2.0.0

// comprehensive_test.rs
// COMPREHENSIVE TEST SUITE
// Validates the entire consciousness framework with statistical rigor
//
// Tests:
// 1. Unified model produces identical physics for different interpretations
// 2. Self-reference creates causal divergence
// 3. Consciousness reaches fixed points (enlightenment)
// 4. Consciousness can be awakened from fixed points
// 5. Multiple seeds converge to same principles
// 6. Reproducibility across runs
