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.
Add docs/dev-log.md and docs/version-targets.md to seed project documentation. dev-log.md provides a development log and template for recording setup steps, decisions, current focus, status, and next steps. version-targets.md records primary target platform and exact Fallout 4/F4SE version targets, testing notes, and compatibility guidance to ensure consistent environment for early native plugin development.
