refactor(core,server): 统一模块职责并消除类型重复

Browse Source 
Core 模块职责:
- 添加 inferPermissionType() 权限类型推断函数
- 添加 partToApiFormat()/partsToApiFormat() API 格式转换函数
- 添加 ApiPart/ApiTextPart/ApiToolPart/ApiReasoningPart 类型
- 统一导出 toolRegistry 供 Server 使用

Server 模块职责:
- 重命名 PermissionRequestContext 为 PermissionDisplayContext
- 移除本地 toolRegistry，直接使用 Core 的注册表
- 使用 Core 的 inferPermissionType 替代本地实现
- 使用 Core 的 partsToApiFormat 替代手动转换

文档更新:
- 在 gui-server-client.md 添加第11章「模块职责边界」
- 明确 Core 和 Server 的职责划分
