[Requests and ideas] option to define target folder when adding project from repo URL

**Mood:** 😊
**Category:** Requests and ideas

My workflow is to keep primary repo clones in specific local folders, for example C:\dev\org\repo, while letting the app manage session worktrees separately in its buckets folder. When I add a project from a repo URL, I’d like to clone the primary repo directly from the app into my desired local path instead of first cloning it manually outside the app and then adding the existing folder. The app currently doesn't provide an option to define the target folder to clone a repo.

首先跟踪应用针对仓库 URL 的 add-project 流程，以及它如何选择克隆目标。确定涉及的 UI 和克隆入口点，然后验证用户选择的本地文件夹是否用于主克隆，而 session worktree 是否仍保留在各自的 buckets 文件夹中。
