[idea] Worktree creating and deletion should be async

[razajamil]

idea / problem

I have an automated workflow where I get herdr to spawn worktrees for a ticket with a bunch of tabs/pans for fix/review/pr. I just cycle through these, check the work and then merge the generated PRs.

The problem is that anytime my factor picks up a ticket (create a worktree) or merges a PR (delete a worktree), the whole UI freezes and I'm unable to do anything for 5-10 seconds which is a bad experience.

requested change

Have a config (or by default) that makes worktree creation/deletion a background process that doesn't block the entire UI.

why you want this

It will make it so that I can hop around difference worktrees and review/approve work without getting stuck.

It's also a pretty bad experience for new user when they create a new worktree for the first time and everything gets stuck for 10 seconds. I almost passed on herdr from my first use but a friend recommended it so I stuck with it an so glad that I did.
