auto-claude: subtask-1-1 - Add --no-track flag to git worktree add command (#1455)

Prevents new worktree branches from inheriting upstream tracking from
the base ref (e.g., origin/main). This ensures users can push with -u
to correctly set up tracking to their own remote branch instead of
incorrectly tracking the base branch.
