"""Service layer for Codebase MCP Server.
This module exports all service implementations for repository indexing,
code chunking, embedding generation, and semantic search.
Service Organization:
- scanner: File scanning with ignore pattern support
- chunker: Tree-sitter AST-based code chunking
- embedder: Ollama embedding generation with retry logic
- searcher: Semantic code search with pgvector similarity
Constitutional Compliance:
- Principle IV: Performance (async operations, caching, batching, <500ms search)
- Principle V: Production quality (error handling, retry logic, validation)
- Principle VIII: Type safety (full mypy --strict compliance)
