Package a standalone client distribution for friends

[PrettyPrincessPotato]

Goal

Create a polished, friend-facing client distribution so players can launch the game without editing source code or manually configuring the client JAR.

Planned work

• Provide a launcher or startup script with a configurable server hostname/IP and port.
• Support easy switching between LAN and public server addresses.
• Optionally provide a standalone client JAR with the server address compiled in.
• Document Java/runtime requirements and launch instructions.
• Package the client with any required cache/resources.
• Make rebuilding straightforward when the server hostname, port, or revision changes.
• Ensure the client remains compatible with the server's revision and RSA configuration.

Current workaround

The client supports:

@echo off
java -jar void-client.jar --address YOUR_HOSTNAME_OR_IP --port 43594
pause

#!/usr/bin/env bash
java -jar void-client.jar --address YOUR_HOSTNAME_OR_IP --port 43594

Acceptance criteria

A friend can download the distribution, install the required Java runtime, and launch the client using a simple script or shortcut without modifying Java source code.
