exclude key in mypy.ini as a single regex doesn't scale for larger code bases

exclude key in mypy.ini as a single regex doesn't scale for larger code bases: a task in MiMo-V2.6-RL-harbor-code: MiMo-V2.6-RL Code (Harbor) (Harbor dataset). I'd like the exclude = in mypy.ini to have a saner way to specify a lot of paths that one huge one-line regex.
