feat: bundle WebView2 Fixed Version Runtime in portable zip

- Set WEBVIEW2_BROWSER_EXECUTABLE_FOLDER env var in main.rs before
  Tauri init, pointing to a 'runtime' folder next to the exe. This
  lets the app use the bundled WebView2 runtime on machines without
  Edge or the Evergreen WebView2 Runtime installed.
- Set webviewInstallMode to skip (no installer needed)
- CI downloads WebView2 Fixed Version cab (133.0.3065.92) from
  westinyang/WebView2RuntimeArchive, extracts it, and packages it
  alongside yauz.exe in the release zip
- Windows release artifact is now YAUZ-windows-x64.zip containing
  yauz.exe + runtime/ folder (~250MB total)
- Bump version to 0.5.4
