Please add default in settings to default multi-repo sessions to 'local' instead of having to manually toggle off the worktree under every single repo. This is particularly difficult when i have a large number of repos in a folder that i want to open and do work on. Currently if i open my large repo folder in github copilot it tries to create worktrees for 93 repos (which basically makes it stuck for a long time). If There is another workflow that allows for easier cross repo work i would be happy to try that as well. Thanks for all your work!

该 issue 没有指出任何文件或测试。首先定位多仓库会话的设置流程和 worktree 切换开关，然后跟踪打开文件夹时如何选择会话模式。完成的标准是，可以通过一项设置将这些会话默认设为 local，而无需手动更改每个仓库；同时，打开大型文件夹时不再默认创建 worktrees。
