Move work to the VM and back, and see when a copy is stale.
Send a worktree with its branch, unsaved changes and Claude sessions. When the Mac and VM copies drift apart, Elsewhere shows which side is ahead and offers a one-click sync in the safe direction. It only fast-forwards, so nothing is overwritten.
- Unsaved work is committed as a WIP commit first
- Refuses to guess when both sides changed
- Claude sessions copied with their paths rewritten
