battledrones v14: Compass Rose, a four player map

The developer added a four-player online mode to Battledrones, whose previous maps were limited to two players, using a prompt asking for a new map with four-way rotational symmetry, up to four AI players, and support for the WebSocket non-audio multiplayer mode so up to four humans can join with spare slots filled by AI. Claude Opus 4.5 added a map called "Compass Rose" and modified the WebSockets multiplayer network code to support up to four players for that map, joining via share links or QR codes. The new teams use purple and green robot themes alongside the existing blue and red designs, previewable in the updated model browser.
