Plan mode constantly cannot update plans with revisions.

Plan mode constantly cannot update plans with revisions. Troubleshooting in the session appears to indicate that the file is being cached and not re-read when the agent updates it on disk; my agent had to actually delete and recreate the plan file to get the view in the canvas to update.

从应用版本 1.1.6 中的 /chat 路径开始，在 Ubuntu 24.4.0 上的 Plan mode 中重现一次计划修订，并观察 canvas 是否会重新读取已更改的计划文件。当修订内容出现在 canvas 中，且无需删除并重新创建计划文件时，即视为完成。
