Fix: InputTextMultiline crashed when drawn (InputTextLineIndexBuild/line offsets 0-based like upstream, inverted buf_display_end), InputText LiveEdit flag check; Shortcut()/IsKeyChordPressed() upstream defaults; FrameCount starts at 0 (IsWindowAppearing on first frame); missing ImGuiIO config fields with upstream defaults (+ ConfigDebugBeginReturnValueOnce/Loop); ColorButton drag source + ColorEdit4 drop target, IMGUI_PAYLOAD_TYPE_COLOR_3F/4F; t_fixes covers them
