Worktree creation was canceled

Error message

Worktree creation was canceled

What it means

Sentinel raised in await_and_rollback_on_failure: one of the per-repository worktree creation receivers was cancelled (dropped before sending a result), so the creation was interrupted and any partially created worktrees must be rolled back.

Solutions

1. Retry the worktree creation; it was cancelled before completion
2. Avoid closing the window or switching workspaces while creation is in progress
3. Check the first_error reported alongside this cancellation for the underlying cause
