andrew 8dfec0a4b3 Rename project to Commonwealth Online

Replace occurrences of "Fallout 4 Together" with "Commonwealth Online" across docs and testing guidance. Add Interface assets and tooling: MainMenu/Pipboy SWFs, translation/fonts, exported scripts (Interface/exported/scripts/MainMenu.as) and a PATCH_MainMenu_Multiplayer.md describing how to add a Multiplayer menu entry that calls root.f4se.plugins.commonwealthOnline.openManager(). Also add build/run batch scripts and apply assorted updates to README, plugin, server and protocol documentation/source to align with the rename and UI changes.

Commonwealth Online

Commonwealth Online is an experimental research project exploring the possibility of adding basic multiplayer-style networking to Fallout 4.

The goal is not to create a full co-op campaign mod immediately. The first goal is much smaller:

Two Fallout 4 clients in a controlled test environment, with each player visible as a synced remote actor.

This project is currently in the research and prototype stage.

Project Goals

First Prototype

Load a native Fallout 4 plugin through F4SE
Connect to a local test server
Send local player position data
Receive remote player transform data
Represent another connected player using a placeholder actor
Restrict all testing to a custom test cell

Long-Term Ideas

Basic LAN multiplayer test mode
Remote player movement sync
Basic animation state sync
Basic chat or debug messages
Host-controlled test cell
Simple co-op combat arena

Non-Goals

This project is not currently trying to support:

Full Fallout 4 campaign co-op
Quest synchronization
Settlement synchronization
Full NPC/world state synchronization
VATS synchronization
Public server/MMO gameplay
Compatibility with large modlists

Those systems are extremely complex and are outside the scope of the first prototype.
