/**
 * CodeEntityGraph — 代码实体关系图谱
 *
 * Phase E: 在 Semantic Memory 之上构建代码实体图谱
 *
 * 节点类型:
 *   - class      : ObjC @interface / Swift class/struct
 *   - protocol   : ObjC @protocol / Swift protocol
 *   - category   : ObjC Category / Swift Extension
 *   - module     : SPM/CocoaPods module
 *   - pattern    : 设计模式 (singleton, delegate, etc.)
 *
 * 边类型 (复用 knowledge_edges 表):
 *   - inherits    : 类继承
 *   - conforms    : 协议遵循
 *   - extends     : Category/Extension
 *   - depends_on  : 模块依赖
 *   - uses_pattern: 使用设计模式
 *   - is_part_of  : 属于模块
 *   - calls       : 方法调用 (Phase 5)
 *   - data_flow   : 数据流向 (Phase 5)
 *
 * @module CodeEntityGraph
