//! Consciousness-Inspired Processing for Quantum-Neuromorphic Fusion
//!
//! This module implements consciousness-inspired algorithms that simulate various
//! aspects of conscious information processing in biological systems. These algorithms
//! are integrated with quantum-neuromorphic processing to create sophisticated
//! image processing capabilities that mirror aspects of conscious awareness.
//!
//! # Consciousness-Inspired Features
//!
//! - **Global Workspace Theory**: Information integration and broadcasting across processing modules
//! - **Integrated Information Theory**: Φ (phi) measures for quantifying consciousness-like information integration
//! - **Predictive Coding Hierarchy**: Hierarchical predictive processing inspired by brain mechanisms
//! - **Meta-Cognitive Monitoring**: Self-awareness mechanisms that monitor processing states
//! - **Temporal Binding Consciousness**: Temporal integration creating conscious moments
//!
//! # Theoretical Background
//!
//! These algorithms are based on leading theories of consciousness from neuroscience:
//! - Global Workspace Theory (Bernard Baars)
//! - Integrated Information Theory (Giulio Tononi)
//! - Predictive Processing Theory (Andy Clark, Jakob Hohwy)
//! - Meta-Cognitive Theory (Terrence Deacon)
//! - Temporal Binding Theory (Susan Greenfield)
//!
//! # Processing Pipeline
//!
//! 1. **Unconscious Processing**: Parallel processing in specialized modules
//! 2. **Competition for Consciousness**: Information competes for global workspace access
//! 3. **Global Broadcasting**: Conscious information influences all modules
//! 4. **Integrated Information**: Φ-weighted processing based on information integration
//! 5. **Predictive Coding**: Hierarchical prediction and error minimization
//! 6. **Meta-Cognitive Monitoring**: Self-awareness and confidence assessment
//! 7. **Temporal Binding**: Integration across temporal windows
