Summary

• Allow remote workspace worktree remove <repo> <branch> to remove a stored worktree row when the handle slug no longer matches the current branch.
• Preserve the existing canonical handle lookup first, then fall back to matching registered remote worktrees by repo_name and branch.
• Add smoke coverage for a reused/stale handle row removed by its current branch.

Verification
