Send Connectionless Packet

Send a connectionless (out-of-band) UDP packet to a QuakeLive or Quake3 server and return the parsed reply. Connectionless packets are raw UDP datagrams prefixed with four 0xFF bytes followed by a command string. Servers that speak the Q3/QL protocol respond in the same format. No prior connection or handshake is required — each call is a single send + single receive. Supported commands (see the `command` enum): • `getinfo` — returns a key-value info string with map, gametype, player count, hostname, sv_fps, and more. • `getstatus` — returns the full info string plus one line per connected player (frags, ping, name). Use this to inspect current players. • `getchallenge` — returns a one-time challenge number (used internally during connection setup). • `rcon` — executes a console command server-side via the remote console interface. Requires `rcon_password` and `rcon_command`. • `ping` — sends a probe and expects an `ack` reply; useful for a lightweight reachability check. The response JSON always includes `response_type` (the first token of the server reply) and `raw` (the full reply text). For `infoResponse` and `statusResponse` an `info` object with parsed key-value pairs is also included; `statusResponse` additionally includes a `players` array.
