v0.25.0

create, checkout and extract reuse an existing local branch.

Breaking

• wtm create <existing-branch> --yes and wtm extract --to <existing-branch> --yes require --from <parent>: wtm cannot guess the parent.

Added

• wtm checkout <PR> reuses an existing local branch instead of asking for wtm clean, and offers to fast-forward it.
• wtm create <existing-branch> and wtm extract --to <existing-branch> reuse the branch, announced in the recap.
• JSON of create and checkout reports whether the branch existed and how it stands against origin.

Changed

• A branch checked out in another worktree exits 10 with a wtm go <branch> hint; --if-not-exists returns that worktree.
