Added XML documentation comments to multiple methods and properties for better API documentation. Streamlined `FfProbeKeyframeExtractor` logic and enhanced EBML parsing code with comments and style improvements. Introduced a new `.editorconfig` to disable legacy StyleCop and IDisposableAnalyzers rules. Updated binary files, assembly info, and NuGet cache files due to rebuilds and dependency changes. No functional changes were made.
Refactored all C# test files to use explicit namespace declarations and moved all using directives inside the namespace block for consistency.
