Delete the NetConnectionUI GameObject from Game/DevSandbox/SampleScene + ConnectionUI.cs (the UITK frontend menu owns Host/Join+IP now); repoint 4 stale doc-comments (GameBootstrap done in commit C; DebugOverlay/ConnectionConfig/EditorAutoHostSystem here) to MainMenuController/WorldLauncher; remove the Assets/_Recovery crash-recovery scenes.
