//! Learning Scenarios Module
//!
//! This module provides patterns and scenarios for training the
//! RuVector self-learning hooks system, with full Claude Agent SDK
//! and MCP integration support.
//!
//! ## Four Attention Mechanisms
//!
//! | Attention Type | Question Answered | Application |
//! |---------------|-------------------|-------------|
//! | **Neural** | What words matter? | Token/semantic relevance |
//! | **DAG** | What steps matter? | Execution order, dependencies |
//! | **Graph** | What relationships matter? | Code structure, call graphs |
//! | **State Space** | What history still matters? | Context persistence |
