Pull request overview

Adds additional upstream pygrep-hooks checks to the repository’s pre-commit configuration to catch a few common Python/text pitfalls earlier in CI and local developer workflows.

Changes:

• Add python-check-mock-methods to detect common invalid unittest.mock method usages.
• Add python-use-type-annotations to discourage PEP 484 type comments in favor of annotations (with a targeted exclude).
• Add text-unicode-replacement-char to forbid UTF-8 replacement characters in committed files.
