v0.2.1

• Fixed the in-flight/menu cursor state so the pointer hides in flight and returns in menus.
• Fixed Return To Lobby so host/client sessions tear down the flight scene, clear aircraft/clones, and reopen the lobby cleanly.
• Added a reconnect grace window for direct UDP peers to prevent brief dropouts from removing players and desyncing remote damage visuals.
• Prevented late aircraft-state packets from recreating remote clones after returning to the lobby.
