//! Strange Loop - Ultra-low-latency agent framework
//!
//! Strange Loop is a Rust-based agent framework designed for nanosecond-precision
//! coordination and ultra-low-latency systems. It provides deterministic agent
//! execution with sub-microsecond timing guarantees.
//!
//! # Features
//!
//! - **Nano-agent system**: Deterministic agents with budget enforcement
//! - **Temporal prediction**: Computing solutions before data arrives
//! - **Lock-free communication**: High-performance message passing
//! - **SIMD optimizations**: Cache-aligned data structures
//! - **Nanosecond precision**: TSC-based timing for accuracy
//!
//! # Quick Start
//!
//! ```rust
//! use strange_loop::nano_agent::{NanoScheduler, SchedulerConfig, SchedulerTopology};
//!
//! let config = SchedulerConfig {
//!     topology: SchedulerTopology::Mesh,
//!     run_duration_ns: 100_000_000, // 100ms
//!     tick_duration_ns: 50_000,     // 50μs
//!     max_agents: 10,
//!     bus_capacity: 1000,
//!     enable_tracing: false,
//! };
//!
//! let mut scheduler = NanoScheduler::new(config);
//! // Add agents and run...
//! ```
//!
//! # Performance
//!
//! - **Sub-microsecond execution**: Agents execute in <1μs
//! - **20,000+ Hz coordination**: Multi-agent synchronization
//! - **Zero allocations**: Lock-free, allocation-free hot paths
//! - **SIMD acceleration**: AVX2-optimized vector operations
//!
//! # Architecture
//!
//! Strange Loop implements a hierarchical agent system where nano-agents
//! operate with strict timing budgets and communicate through lock-free
//! message buses. The system is designed for real-time applications
//! requiring deterministic behavior.
