Privelto portable

Extract the entire archive into a writable folder before launching.
Do not run the executable from inside the archive. Keep the marker beside the application.
Application models, runtime, preferences and logs are stored in PriveltoData next to the application.
The first launch downloads the required model/runtime pack; offline import is supported.
Move the whole folder, including PriveltoData, to retain the portable profile.
Operating-system and GPU-driver caches can still exist outside this folder.
Windows requires Microsoft Edge WebView2 Runtime, installed separately when needed.
