Introduced the `Client.Workflows` feature to enable combined
operations with pre-validation. Added the method
`ExtractSwissQrCodeValidatedAsync()` for extracting Swiss QR
Code data with validation in one step.
Updated the README to document the new feature, including
usage examples in C#, VB.NET, and PowerShell, details on the
`throwIfInvalid` parameter, and method signature.
Added the method to the API Endpoints section with a note
about its current `NotImplementedException` status. Clarified
the use of `[Obsolete]` for unimplemented endpoints. Enhanced
the PowerShell note to recommend threading for long-running
operations.
Enhanced README with German translation and examples.
- Added German translation to README alongside English content.
- Expanded installation, configuration, and usage examples.
- Documented static `Client` entry point and error handling.
- Removed STREAM_API_DESIGN.md as it is no longer relevant.
- Changed solution configuration to build in Release mode by default.
