feat(v0.4): TUI 系统监控面板 + 插件状态面板

v0.4.1 系统监控面板:
- 复用共享 SystemInfoCollector (TUI + Web面板同一数据源)
- CPU/MEM 彩色进度条 + 网络实时速率
- 2 秒刷新，set_interval 驱动

v0.4.2 插件状态面板:
- 展示已加载插件的名称/版本/命令数
- 3 秒刷新，PluginService 延迟注入

SystemInfoCollector:
- 注册为共享服务 (sys_collector)
- Web panel status.py 优先从 service_manager 获取
- 零重复数据采集

TUI 布局升级: 3行 → 4行 (monitor + log + message + input)
