/**
 * Solidity AST indexer — consumes Hardhat build-info JSON to produce a
 * richer devgraph: representation than the regex-based pass in indexer.ts.
 *
 * Input:  `<pkgDir>/artifacts/build-info/*.json` (Hardhat combined solc input/output).
 * Output: `Quad[]` extending the existing Contract/Function/Event vocabulary with:
 *   - StateVariable / Event / Error / Modifier as first-class classes
 *   - visibility, stateMutability, functionKind, isAbstract, isConstant,
 *     isImmutable, isVirtual, contractKind, license, solidityVersion, docstring
 *   - usesModifier (Function → Modifier), emitsEvent legacy string kept for
 *     back-compat, plus emits (Function → Event) when the body emits a known
 *     event definition
 *   - calls (Function → Function) within the same build-info via AST node id
 *     resolution — covers internal calls; cross-contract calls resolve when
 *     the callee is in the same build-info
 *
 * URI scheme (stable across regex and AST passes for Contract / Function):
 *   - Contract:      symbol:<repo-rel-path>/contract/<name>
 *   - Function:      symbol:<repo-rel-path>/fn/<name>#<astId>
 *   - Event:         symbol:<repo-rel-path>/event/<name>#<astId>
 *   - Error:         symbol:<repo-rel-path>/error/<name>#<astId>
 *   - Modifier:      symbol:<repo-rel-path>/modifier/<name>#<astId>
 *   - StateVariable: symbol:<repo-rel-path>/var/<name>#<astId>
 *
 * The AST id suffix on functions disambiguates overloads and anonymous kinds
 * (constructor/receive/fallback) while leaving a stable, reproducible URI.
