/**
 * @module lang-dart
 * @description Dart AST Walker 插件
 *
 * 提取: class, mixin, extension, enum, typedef, function, method, field, import
 * 模式: Flutter Widget (Stateless/Stateful/Consumer), Factory, Singleton,
 *        Builder, BLoC/Cubit, Provider/Riverpod, Freezed
 *
 * Phase 5: 新增 ImportRecord 结构化导入 + extractCallSites 调用点提取
 *
 * 注意: tree-sitter-dart 目前尚无兼容 tree-sitter ≥0.25 的稳定版。
 *       已迁移至 web-tree-sitter (WASM)，无原生编译依赖。
