CodeGraph CLI MCP Server

# CodeGraph Vector (`codegraph-vector`) ## Overview `codegraph-vector` is responsible for the "AI" part of the graph generation—specifically, creating vector embeddings for code nodes. ## Key Features ### Chunking Code is often too large for a single embedding vector. - **Smart Chunking**: Splits code based on semantic boundaries (functions, blocks) rather than just line counts, ensuring coherent embeddings. ### Embedding Generation - **Provider Abstraction**: Supports multiple backends (OpenAI, Ollama, Local ONNX models via `ort`). - **`EmbeddingGenerator`**: The main interface for converting text to `Vec<f32>`. ### Integration Used by `codegraph-mcp` to enrich `CodeNode`s before persistence.
