fix(v8.0): 启用真·全屏 textual TUI 并修复 opacity 崩溃
- 修复崩溃: tui.py MessageBubble.on_mount 用 self.animate('opacity')，但
textual>=8 的 Widget.opacity 为只读属性会抛 'has no setter'，导致每条消息
气泡崩溃 -> 改 styles.animate 并兜底直接设置。
- run_tui 改为默认真·全屏 textual XiaoliTUI（上方滚动聊天区+底部固定输入框+侧栏），
rich 面板仅作 textual 不可用时的回退（此前默认的是顺序面板，被指出是'假TUI'）。
- 版本统一 v8.0.0: 欢迎框 + /about 改用 VERSION 常量。
- 状态栏联动 token 感知: 显示 used/context_window 进度条（引擎支持时）。
- 新增 /snapshot(/screenshot) 命令: 导出当前屏幕 SVG 到 .tui_snapshots/live.svg，
让实时 TUI 也能被 AI 自验。
- 新增 tools/tui_real_snapshot.py: textual run_test+Pilot 无头驱动真实 TUI，
喂对话、断言 DOM（用户/工具成功失败/助手/状态栏/token条/欢迎版本），导出 SVG。
7 项断言全过。
- 注: launcher 启动会重写 plugins_config.py/requirements.txt(含 tkinter 等错误项)，
提交前已还原，避免误提交漂移。

v8.0 真·全屏 TUI（textual）无头自验 + 截图
|
||||
==========================================
|
||||
用 textual 的 App.run_test() + Pilot 无头驱动真实 XiaoliTUI：
|
||||
- 断言 DOM 结构（滚动聊天区 / 底部输入框 / 侧栏 / 状态栏）
|
||||
- 模拟输入并发送一轮对话，驱动 cli.tui_output_callback 渲染气泡
|
||||
- 断言渲染结果，导出 SVG 截图到 .tui_snapshots/real_demo.svg
|
||||
AI 可据此自验"真 TUI 长啥样"，无需人工截图。
