refactor: 移除插件内存管理系统 + 新增工作流引擎

移除内容:
- 删除 plugin_memory_manager.py (TTL淘汰 + 懒加载系统)
- unified_tool_manager.py 精简为直接加载，去掉内存管理器集成
- tui.py 移除内存管理状态显示

新增内容:
- plugins/workflow.py: YAML 工作流引擎
  - 顺序执行多步骤 (tool/shell/echo/wait/set/if)
  - 步骤间变量传递 ({{steps.name.output}})
  - 条件分支 (if/then/else)
  - 错误处理 (continue_on_error / on_fail)
  - 断点续跑 (状态持久化)
  - 调用其他插件作为步骤
- workflows/example.yaml: 示例工作流

修复:
- unified_tool_manager.shutdown() 增加 graceful cleanup
- unregister_tool() 增加实例清理

   - `/status` 命令和 TUI 侧栏实时显示内存管理状态（已加载/已卸载/统计）
   - `search_tools` 支持搜索已卸载插件（使用缓存的元数据，无需加载实例）
 
+###  统一插件格式
+
+- **统一自研插件入口类名为 `Liugin`** — 18 个插件从 `class Plugin` 统一为 `class Liugin`
+  - 加载器保留 `Plugin` 回退兼容，第三方插件仍可用旧格式
+  - 测试块中 `Plugin()` 调用同步更新为 `Liugin()`
+
 ###  TUI 修复
 
 - **修复消息分类失效** — `_write_raw` 中空字符串 `'' in msg` 永远为 True，导致所有消息显示为工具成功样式；替换为正确的 emoji 标记（✅/❌/🤖）

-  1. 每个插件记录 last_used 时间戳
-  2. 后台线程定期扫描，超过 TTL 未使用的插件从内存卸载
-  3. AI 调用已卸载的插件时，自动重新加载
-  4. 核心插件（tool_search 等）可钉住，永不淘汰
-
-配置:
-  - plugin_ttl: 插件空闲多久后淘汰（秒），默认 300（5分钟）
-  - max_idle_plugins: 最多保留多少个空闲插件，超出后淘汰最久未用的，默认 10
-  - check_interval: 后台扫描间隔（秒），默认 60
