/**
 * @module AstAnalyzer
 * @description 基于 Tree-sitter 的多语言 AST 分析器（插件注册制）
 *
 * 提供结构化代码分析能力：
 * - 类/协议/扩展 声明与继承关系
 * - 属性声明与修饰符
 * - 方法签名（类方法/实例方法）
 * - 设计模式检测（Singleton、Delegate、Factory、Observer）
 * - 代码结构指标（圈复杂度、嵌套深度、方法行数）
 *
 * 支持语言：通过插件注册 — ObjC、Swift、TypeScript、JavaScript、Python、Java、Kotlin、Go、Dart、Rust
 * 插件注册入口: lib/core/ast/index.js
