Upgrade support is manual (for now). When a new worktree is added, we

But that's it. We can't safely bump 1 to 2 automatically.

Maybe, bumping should happen only if there is no worktree so
far. If there is already, then worktree left to be 0 or
whatever it is. Then it can be bumped directly to the last
supported version.

Otherwise sounds ok. I have checked how it works and did not
read the code carefully, since you it's not ready yet.
