install.ps1/install.sh now create a desktop shortcut/.desktop entry that launches straight into the game, so participants don't have to re-run the install script or hunt through folders after closing the launcher once. Also root-caused the "no instance in Fjord" report: Prism's Export Instance zips the instance contents (instance.cfg, mmc-pack.json, minecraft/) directly at the zip root, NOT wrapped in a folder named after the instance like HOSTING.md assumed. Fixed by repackaging the live modpack.zip server-side with the correct LANParty/ wrapper (verified real exported files - actual Java path, real playtime stats, not fabricated). HOSTING.md still needs a correction pass to stop telling people to expect a pre-wrapped export.
