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.
Replace CommonLibF4 template identity with Fallout4Together across README, setup and xmake; update developer log with build/test entries. Implement player transform tracking in src: add PlayerTransform struct, change detection (position + wrapped Z rotation), throttling (minimum interval), and logging to Fallout4Together.log. Wire up F4SE messaging listener and a permanent task to poll on the game thread; include <chrono> and update startup log message. Add warnings for missing task/messaging interfaces and when player reference is unavailable.
