Display hardcore heart textures when a world is in hardcore mode, matching Java Edition behavior. Hearts switch between normal/hardcore across all states (poison, wither, flash) and all HUD resolutions. C++ changes: - IUIScene_HUD: check isHardcore() and call SetHardcoreMode() each tick - UIScene_HUD: send hardcore boolean to Flash via Iggy, invalidate SetHealth dirty check on state change to force heart redraw - CreateWorldMenu/LoadMenu: lock game mode to Survival when hardcore - MinecraftServer: gate server.properties hardcore override behind MINECRAFT_SERVER_BUILD so offline worlds preserve their saved flag SWF changes (via new Java tools): - AddHardcoreBitmaps: adds 10 hardcore heart bitmaps to graphics SWFs - AddHardcoreHearts: adds 10 new frames (15-24) to health sprite - PatchHudABC: patches HUD ActionScript bytecode with SetHardcore method and frame offset logic (+14 normal/poison, +6 wither) Also updates README changelog styling with consistent ### headings.
