Research direction

Locate the existing chapter on CGroups in the repository (likely a Markdown file in the cgroups directory). The chapter currently covers only cgroups v1. Research the differences between cgroups v1 and v2, including resource controllers, interface files, and management tools. Add a new section explaining cgroups v2, its advantages, and migration considerations. No additional comments from maintainers, so the scope is defined by the title.
