feat: 实现基于文件模式的灵活资源发现架构

## 🏗️ 新增 FilePatternDiscovery 基类
- 统一的文件模式识别逻辑，支持 .role.md, .thought.md, .execution.md, .knowledge.md, .tool.js
- 递归扫描任意目录结构，完全基于文件扩展名识别资源类型
- 统一的资源验证和引用路径生成机制

## 🔄 重构 ProjectDiscovery 和 PackageDiscovery
- 继承 FilePatternDiscovery 基类，大幅简化代码
- 子类只需重写 _getBaseDirectory() 指定扫描目录
- 移除重复的文件扫描和验证逻辑，提升维护性

## 🎯 实现完全灵活的目录结构支持
- resource/ 下支持任意目录组织方式
- 目录名称仅有语义意义，不影响资源发现
- 支持深层嵌套和扁平化结构

## 🔧 修复 InitCommand 参数处理
- 优化空对象参数的处理逻辑
- 保持向后兼容的同时提升健壮性

## ✅ 测试验证
- welcome/action/init 命令全面测试通过
- 包级61个资源 + 项目级8个资源正确发现
- project 协议和工具文件识别正常工作
