Crow Translate 4.0.2 released

[pillowtrucker at proton.me]

We're proud to announce the first Qt6 release of Crow Translate!
The files can be found at https://download.kde.org/stable/crow-translate/4.0.2/
The public key corresponding to the signatures should be attached to this e-mail.
Highlights:

-   Qt6 Migration: Complete port from Qt5 to Qt6 with improved performance and compatibility
-   Provider System: Complete architectural rewrite with modular translation and TTS providers
-   Qt TTS Provider: System text-to-speech integration via Qt6 TextToSpeech
-   Neural TTS: Added high-quality Piper neural text-to-speech with ONNX Runtime integration

The inspiration for the architectural changes was the fact that most Mozhi instances seem to immediately get banned from the cloud TTS, effectively disabling the feature. We recommend using the Piper TTS backend for best reliability and quality. The neural network models can be found at https://huggingface.co/rhasspy/piper-voices - the application will also display this url and instructions for setup on first activation of the backend, if no models are present.
CAVEAT: The Qt TTS backend is known to be broken on Windows in Qt versions 6.9.1-6.9.2, the Windows release artifacts on our CDN are built against and shipped with Qt 6.8.3 libraries.

The upcoming 4.1 release will feature, among other improvements, a local translation backend for full offline functionality.
