Refactor tests and enhance documentation across files

- Adjusted assertion indentation in `PerformanceStopwatchTests`.
- Removed commented-out code in `IEasyDisposableTests` and `IEasyDisposable`.
- Updated `Add` method in `ObservableList` to indicate future void change.
- Added future task comments in `ComputerInfo` for CPU metrics and static methods.
- Enhanced documentation in `StartNewWithTelemetry` with an optional `title` parameter.
- Indicated potential changes in `IDataModel` to use `string` instead of `TKey`.
- Added comments for future method renames and changes in `Validator`, `ListExtensions`, `DirectoryHelper`, and `FileProcessor`.
- Noted future enhancements in `HttpClientHelper` for retry logic.
