nano-consciousness 0.1.0

//! # Nano-Consciousness AI System
//!
//! A high-precision temporal consciousness framework combining ruv-FANN neural networks
//! with nanosecond-precision scheduling for real-time AI applications.
//!
//! ## Core Features
//!
//! - **Nanosecond Scheduling**: Ultra-precise task timing with <100ns overhead
//! - **Temporal Windowing**: Sliding windows with configurable overlap for continuity
//! - **Neural Integration**: Seamless ruv-FANN integration with temporal traits
//! - **Plasticity Extensions**: STDP learning and phase-coding support
//! - **Cross-Platform**: Native x86_64 and WebAssembly support
//! - **Stability Constraints**: Lipschitz continuity for convergent behavior
//!
//! ## Architecture
//!
//! The system is built around two main layers:
//!
//! 1. **Neural Layer**: ruv-FANN networks wrapped with temporal behaviors
//! 2. **Scheduler Layer**: Nanosecond-precision task orchestration
//!
//! ## Example Usage
//!
//! ```rust,no_run
//! use nano_consciousness::{
//!     NanoConsciousnessSystem, SchedulerConfig, TemporalConfig
//! };
//!
//! let config = SchedulerConfig {
//!     tick_rate_ns: 1000,    // 1μs precision
//!     max_tasks: 10000,
//!     lipschitz_constant: 0.9,
//!     ..Default::default()
//! };
//!
//! let temporal_config = TemporalConfig {
//!     window_duration_ns: 100_000,  // 100μs windows
//!     overlap_percent: 50.0,        // 50% overlap
//!     ..Default::default()
//! };
//!
//! let mut system = NanoConsciousnessSystem::new(config, temporal_config)?;
//! system.start_consciousness_loop().await?;
//! ```
