Smarter protocol handling and safer connections

This release focuses on how Atrahasis PRO talks to your servers under the hood.

• Smarter protocol negotiation. The app now settles on the fastest transport a server offers more reliably
• Refined HTTP/3 support. HTTP/3 request handling has been improved, so POST, PUT and PATCH calls carry their data consistently across protocols.
• Stronger connection security. Server certificate validation now applies uniformly, whether a connection runs over HTTP/1.1, HTTP/2 or HTTP/3.
• Clearer error reporting. When a connection can't be established, Atrahasis surfaces the underlying cause instead of falling back to a vague timeout message.
• Self-updating User-Agent. The default User-Agent header now tracks the installed build automatically, so it stays in step with the app version.
