Summary

I configure my hooks that never modify files to run at the end in parallel, with priority 99. Of these 2 hooks, I believe basedpyright always takes longer than tombi-lint. After tombi-lint finishes running, it disappears from the UI until basedpyright finishes running, then it reappears at the end.
