BlackMark 549b91a9ce Add coop_mock_game: animated, frame-numbered A/V test game (DX11 + DX12) ...

A tiny test "game" for exercising the capture/audio/hook paths. Opens a normal
window and renders an animated pattern -- moving bar + per-frame background so
motion (and dropped frames) are obvious -- with a top-left block whose RGB
encodes the exact frame number, so a capture test can decode it and detect
dropped / duplicated / stale frames. Selectable backend (dx11 / dx12 today),
behind a RenderBackend interface so OpenGL/Vulkan can be added. With audio args
it also plays a configurable WASAPI tone (shared ToneSource), so it's a full A/V
source with a window (unlike coop_tone).

  coop_mock_game.exe [dx11|dx12] [seconds] [rate] [channels] [bits] [pcm|float]

Milestone 1 of the mock-game roadmap item (the stress-test suite follows).
