/**
 * Code graph indexer — parses a monorepo into devgraph: RDF quads.
 *
 * Extracts:
 *   - Package (workspace deps) from package.json
 *   - CodeModule (source files) with import edges
 *   - Function / Class declarations with signatures
 *   - Contract (Solidity) with inheritance and events
 *   - Python module/class/function extraction (regex-based)
 *
 * Uses ts.createSourceFile (AST-only, no full compilation) for TypeScript/JavaScript
 * and regex-based extraction for Solidity/Python.
