🟢 Approval recommended

The changes are documentation-only and the known-failures baseline updates align with the documented enums, with only a minor documentation wording suggestion noted.

Pull request overview

This PR improves API documentation quality for AppKit by replacing placeholder XML documentation with complete summaries for ten enum types (and their members) in src/AppKit/Enums.cs, and then removing the corresponding Cecil documentation known-failure entries so the doc tests reflect the new coverage.

Changes:

• Added XML <summary> documentation for ten AppKit enum types and their values (replacing “To be added.” placeholders).
• Removed the now-resolved type entries from tests/cecil-tests/Documentation.KnownFailures.txt to keep the documentation baseline up to date.

File summaries
