Wails v3 Alpha Release - v3.0.0-alpha.68

Add Web API examples in v3/examples/web-apis/ demonstrating 41 browser APIs including Storage (localStorage, sessionStorage, IndexedDB, Cache API), Network (Fetch, WebSocket, XMLHttpRequest, EventSource, Beacon), Media (Canvas, WebGL, Web Audio, MediaDevices, MediaRecorder, Speech Synthesis), Device (Geolocation, Clipboard, Fullscreen, Device Orientation, Vibration, Gamepad), Performance (Performance API, Mutation Observer, Intersection/Resize Observer), UI (Web Components, Pointer Events, Selection, Dialog, Drag and Drop), and more
Add WebView API compatibility checker example (v3/examples/webview-api-check/) that tests 200+ browser APIs across platforms
Add internal/libpath package for finding native library paths on Linux with parallel search, caching, and support for Flatpak/Snap/Nix
WIP: Add experimental WebKitGTK 6.0 / GTK4 support for Linux, available via -tags gtk4 (GTK3/WebKit2GTK 4.1 remains the default)
- Note: On tiling window managers (e.g., Hyprland, Sway), Minimize/Maximize operations may not work as expected since the WM controls window geometry
