fix: detect existing EA Desktop install, skip MSI extraction if Link2EA.exe present
On native Linux Steam, EA App self-installs via EAappInstaller.exe on first SWBF2 launch. Link2EA.exe appears in the Wine prefix without any MSI extraction. Script now checks for Link2EA.exe first and skips steps 2-3 (MSI locate + extract) if EA Desktop is already installed, proceeding directly to writing registry fix files and the launch wrapper.
