• update mypy-docs doccmd command string to run mypy --num-workers=4

Note

Low Risk
Low risk configuration-only change that only affects local pre-push type-check runs by enabling mypy parallelism.

Overview
Speeds up local type-checking by enabling mypy parallel workers in the pre-push hooks.

Updates the mypy hook to run mypy --num-workers=4, and adjusts the mypy-docs doccmd command string to include the same flag (with formatting aligned to the YAML style).
