CodeGraph CLI MCP Server

# CodeGraph Graph (`codegraph-graph`) ## Overview `codegraph-graph` serves as the Data Access Layer (DAL) for the system, specifically targeting SurrealDB as the persistent store. ## Key Components ### `SurrealDbStorage` The main client struct for database interactions. - **Async Operations**: Optimized for high-throughput, concurrent writes. - **Graph Operations**: Methods to insert nodes, create edges, and query the graph. ### Schema & Models Defines the storage-optimized versions of core types. - **`CodeEdge`**: Represents a fully resolved edge in the database. - **`NodeEmbeddingRecord`**: storage for vector embeddings. ## Migration Includes utilities for applying SurrealDB schema files (`.surql`) to ensure the database structure matches the code expectations.
