Research direction
Start in windows/birdlock/app/state.py at export_to() (around line 1406) and compare it with _rebuild_now(), which already shows the background-thread pattern; read how on_main is used elsewhere to publish state back to the UI. The first step is confirming which of RenderJob's steps (plan, compose_plan, deflicker_gains, project_frames, arrange) run in the constructor and need the worker thread. Done means clicking export on a long project no longer blocks the window, with status updates marshalled through on_main; the maintainer notes this was not reproduced on Windows, so a manual check is part of finishing.
Written by the indexing model from the issue text.
Description
位置：windows/birdlock/app/state.py:1406
现象：export_to() 在 self.stop() 后直接 RenderJob(...)，而普通设置变化走 _rebuild_now() 的后台线程。RenderJob 会执行 plan、compose_plan（含防抖与 motion 解析）、deflicker_gains、project_frames、arrange，长视频点击「导出」时主线程会卡住。
复现：打开长视频工程，点击导出，观察窗口无响应时间。
建议：把构造移入 worker 线程，完成后经 on_main 更新状态。
