[antonwolfy]

Summary

• Migrate clang-format from pocc/pre-commit-hooks to pre-commit/mirrors-clang-format v22.1.0
• Update .clang-format config to maintain consistent code style across versions

• Add reformatting commit to .git-blame-ignore-revs

Changes

Pre-commit configuration

• Switch to pre-commit/mirrors-clang-format (v22.1.0) for better version pinning and consistency across environments
• Add --disable=c-extension-no-member to pylint to avoid false positives on C extension objects

Code style

• Update .clang-format: Set AfterControlStatement: Never to preserve existing brace placement style
• Reformat all C++ source files with clang-format v22 (net -159 lines due to template parameter formatting improvements)

Pylint configuration

• Add extension-pkg-allow-list = ["numpy"] to help pylint understand numpy better
• Add generated-members patterns to handle dynamically created attributes on numpy types

CI/CD

• Remove obsolete apt-get install clang-format-12 step from pre-commit workflow
