Subject: [PATCH] Simplify worktree deletion: use git worktree remove instead
 of rename-to-temp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The old approach renamed the worktree directory to a temp path before
deleting it, which raced with the filesystem watcher — the project's
worktree scanner would try to canonicalize the temp path while it was
being deleted, producing 'root path could not be canonicalized' errors.

Now we call git worktree remove --force first, which handles both the
git bookkeeping and directory deletion atomically. Manual fs removal
is only used as a fallback if git can't do it.
