- 版本立项: constants.VERSION=8.0.0，about.txt/README 同步。 - Rich 面板式 TUI (xcli_core/rich_tui.py): 默认 TUI 渲染器，rich 驱动； 核心创新=快照出口(Console(record=True) -> text/svg/html)，AI 开发界面 时可把渲染读回自验，补上'看不见渲染'闭环。tools/tui_snapshot.py 无头生成 演示快照。run_tui 优先 RichTUI，textual 作为回退。 - Token 感知压缩: openai_engine 捕获 usage.prompt_tokens -> last_prompt_tokens， 新增 context_window()(模型名查表 MODEL_CONTEXT_WINDOWS + config 覆盖)； memory.should_compress 升级为 token 感知(used/context_window >= ratio 触发， 默认 0.7)，消息数阈值兜底；cli_core.process_conversation 自动压缩并提示。 - 记忆模式增强: 保留 v5.4.1 的 MEMORY.md/日记/自动保存/AI 摘要压缩，新增 /compress 手动压缩 与 /memory mode <companion|work> 切换。 - requirements 加 rich；.gitignore 忽略 .tui_snapshots/。
