bd76b897de Fix missing newlines in Minecraft RCON messages: 
Minecraft servers have a longstanding bug that omits newlines
when sending messages via RCON. This patch manually inserts
newlines to address the issue.

5f460e8912 Remove Valve protocol checks and set select() timeout to 1.5 seconds 
Use the same method for handling multipacket responses across all servers.

6fed74ba74 Implement select() loop to receive all incoming packets: 
Send a "multipacket guard" - an empty packet with an invalid 'cmd' field
and a unique packet ID to trigger a reply from the server once the previous
command's reply has been fully sent.

Valve returns an empty payload, while Minecraft includes an error message in the payload.

This workaround ensures that all packets related to the last valid command
are received from the server, avoiding the need to wait for the select() timeout.
