feat: 实现 Hook 系统

参考 open-code 的实现，添加工具执行前后的 hook 功能：

- 添加 Hook 类型定义 (tool.execute.before/after, file.edited/created/deleted 等)
- 实现 HookManager 管理器，支持插件注册和事件触发
- 实现配置文件加载器，支持 .ai-assistant.json/jsonc 格式
- 支持 glob 模式匹配文件触发 shell 命令
- 集成到 Agent 工具执行流程
- 添加 minimatch 依赖用于 glob 匹配
- 编写完整测试用例 (27 个测试)

配置示例:
```json
{
  "hooks": {
    "file_edited": {
      "*.ts": [{ "command": ["npx", "tsc", "--noEmit"] }]
    }
  }
}
```
