Add render_dx09.cpp (selectable as `dx9ex` / `dx9`): renders the animated
pattern with Clear + ColorFill (D3D9's built-in rect fill -- no shaders) and
presents through a real D3D9 / D3D9Ex device. Two modes so the two D3D9 capture
paths each have a matching game. Smoke-verified: both present frames and exit
cleanly. The capture hook + frame-decode test land next.

Add render_dx10.cpp (selectable as `dx10`): composes the animated pattern
(background + moving bar + top-left frame-counter block) on the CPU each frame
and CopyResource's it into a real D3D10 DXGI swap-chain back buffer (DX10 has no
rect-clear; no shaders). Smoke-verified: `coop_mock_game dx10 2` presents frames
and exits cleanly. The frame-accurate decode-through-the-hook assertion lands
with the DX10 capture commit next.

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).

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