Add XML documentation

[christianhelle]

Enhance the codebase by adding comprehensive XML documentation to all publicly accessible types, methods, and properties

All changes were made using Claude Sonnet 4, with the following prompt:

Add XML-style C# documentation comments to all publicly accessible types and members in the codebase. This includes classes, interfaces, structs, enums, methods, properties, events, and fields that are public or protected. The documentation should provide clear and concise summaries that explain the purpose and usage of each type or member.

Tasks:
- Review the codebase to identify all publicly accessible types and members
- Add or improve XML <summary> documentation for each
- Ensure the summaries are meaningful and follow C# documentation best practices
- Optionally, add documentation for parameters, return values, and exceptions where appropriate
- Validate the documentation using tooling (such as analyzers) if available

This will improve code readability, maintainability, and support for tools like IntelliSense.

Commit every single file individually to git to make the progress of this task as transparent as possible
