Ladies and gentlemen, we got him. 🐧

Changes

• Added Wine detection and automatic compatibility fixes.
• Enabled software rendering and fixed black borders and rounded corners.
• Fixed the cursor getting stuck in resize mode.
• Added a warning when WebView2 is missing.
• Disabled unused file drop handling to prevent crashing under Wine.
• Applied compatibility fixes to the in-game overlay but it doesn't work at the moment.
• Fixed excessive CPU usage caused by Tokio's UDP readiness polling under Wine by using blocking sockets via spawn_blocking. Native Windows keeps the original implementation as is

Testing

Tested on: CachyOS (Arch-based), KDE Plasma, Proton-CachyOS 11.0 via umu-launcher, WebView2 156.

• Launcher starts, server list loads, input works smoothly, and idle CPU usage remains low (~0.3 s CPU time per 10 s).

Not yet tested on other Linux distributions/Wine versions, and native Windows.

In-game overlay doesn't work.

Development note

This PR was developed with AI assistance for Rust code. I've reviewed and tested the changes, but my Rust knowledge is limited (Almost 0 tbh), so I'd appreciate a review from someone more experienced with Rust.
