Using mypy 2.0 flag with pinned 1.20.2 version

High Severity

The --num-workers=4 flag is a mypy 2.0 feature (parallel type checking), but the project pins mypy[faster-cache]==1.20.2 in pyproject.toml and uv.lock. Since uv run --extra=dev -m mypy resolves to the locked 1.20.2 version, both the mypy and mypy-docs hooks will fail with an unrecognized argument error. The mypy 1.20 release blog and release planning issue (#20726) confirm parallel type checking was planned exclusively for 2.0.
