[Bug]: 问了一个问题，运行过程中卡死

### What happened?

在 vscode 里面打开 `trae-cli interactive` 问了一个总结项目的问题，界面直接卡着动不了，这个界面看上去很卡，回答完之后才能正常操作。
以及整体操作不够键盘友好，感觉可以优化一下 UX。

### What did you expect to happen?

是否考虑将界面渲染与 Agent Core 部分解耦，界面渲染部分使用 Ink（参考 gemini-cli，使用 React 进行响应式渲染）来实现，agent core 部分可保留 Python？或者其实全部使用 node/bun/deno 来实现也行。

### Traceback

_No response_

### What is your system, Python, dependency version?

- macos
- python3.13

### Additional information that you believe is relevant to this bug

_No response_

Start by reproducing the freeze with `trae-cli interactive` in VS Code while asking for a project summary on macOS with Python 3.13. Inspect the boundary between the interactive UI rendering and Agent Core, then compare the proposed Ink/React approach with gemini-cli. Done should mean the interface remains responsive during responses and supports more keyboard-friendly operation.
