fix: move the #387 resize evidence line into the typed owner

GameWindowSlice8BoundaryTests.FramebufferResize_IsOneTypedOwnerHandoff
correctly rejected the log line added to GameWindow.OnFramebufferResize
— the window callback is contractually a one-line handoff. The line now
lives in FramebufferResizeController.Resize after its zero-size gate,
which is also the better home (one owner, all callers covered). Full
Debug App suite 4,941/3 skips.
