Add mock-game capture/audio/hook stress test

Browse Source 
mock_game_test launches coop_mock_game (DX11/DX12, frame-numbered A/V), injects
coop_hook.dll, opens the hook's shared video texture, and decodes the frame
number from the captured pixels to assert a monotonic, advancing mirror for
both backends (catches dropped/stale/out-of-order frames). Then it runs an
A/V + hook/unhook stress pass and confirms no crash + capture resumes. Adds a
read_pixel() readback to the shipping SharedTextureSource for the decode.
Robust to repeated/CI runs (kills stray games, retries inject). Trim the
roadmap (the mock-game item is done) and document the test.
