Frontend menu + settings + saves foundation

Netcode frontend pattern: UITK main menu / pause / settings (MenuUi + controllers), on-demand world lifecycle (WorldLauncher/SessionRunner), GameBootstrap menu branch; Graphics/Audio settings (SettingsService/GameVolume); single-slot save foundation (SaveData/SaveService, born-correct load at director spawn, autosave on Siege->Calm + quit); RuntimePanelSettings + theme; BuildTool menu; 10 EditMode tests.
