VAAPI-first on desktop RADV (46b7ffc0) was a regression: Vulkan Video decode
outperforms VAAPI on AMD (on-glass verdict). Vulkan-first is safe there since
the same commit's failure-streak demotion lands on VAAPI, not software — a
broken Mesa Vulkan path still ends up on the working driver.
Auto's order is now: Vulkan first on NVIDIA (no usable VAAPI) + all AMD
(perf; VanGogh additionally chroma-fringes over VAAPI); VAAPI first stays on
Intel/unknown (ANV's Vulkan Video is the least-proven Mesa path). Policy test
updated; 26 pf-client-core tests + clippy green on Linux.
