symgraph vs crg

symgraph: Symgraph is a semantic code intelligence server built in Rust that creates knowledge graphs of codebases. It provides advanced code analysis features to enhance AI-assisted code exploration and understanding.; crg: `crg` (formerly `better-code-review-graph`) is a local-first knowledge graph tool for codebases, enabling token-efficient code reviews through semantic search, call-graph resolution, and structural analysis. It integrates with AI agents via MCP for precise context provision, leveraging local ONNX embeddings or cloud models for enhanced code understanding and security scanning.
