SWBF2 (AppID 1237950) launches, calls ShellExecute("link2ea://..."),
and exits. Without a link2ea:// URL protocol handler registered in the
Wine registry, ShellExecute returns error 31 and the game never plays.
_apply_ea_fix now also writes the link2ea:// Classes registry keys
pointing to EADesktop.exe when it is found in the Proton prefix. If
EADesktop.exe is not yet present (EAappInstaller runs async via
RunType=1 in installScript.vdf), the function warns and skips the
handler registration with instructions to run wait-ea-app.
New 'wait-ea-app [appid]' subcommand polls every 15 seconds (up to 20
minutes) for EADesktop.exe to appear, then calls _apply_ea_fix so the
full fix including the link2ea:// handler is applied automatically once
EA App finishes installing in the background.
