srcgraph-core

Graph model, traits, and GraphML I/O shared by the srcgraph metric crates.

• Traits: ClassNode, EdgeKind — the minimum interface every algorithm needs from a graph.
• Owned types: OwnedGraph (wraps petgraph::Graph), OwnedClassNode, EdgeType.
• GraphML reader/writer for the schema produced by the visiting code-analysis extractor: node attrs include id, name, namespace, lineCount, methodCount, plus JSON-encoded per-method fields in semantic mode (methodConnectivity, methodFingerprints, methodTokens, callSequences, cyclomaticComplexity, pathConditions, invariants, errorMessages, magicNumbers, deadCode, tenantBranches, stateTransitions).

Designed so consumers — srcgraph-metrics and external graph stores like yah's kg-store — can run the algorithms generically over any petgraph::Graph<N, E> where N: ClassNode, E: EdgeKind.
