release: prepare 0.1.5 with RDNA2 kernels and in-game DLSS/FSR switching
- Add native preset K kernels for gfx1030–gfx1036 using software matrix products, with fast and accuracy builds and RDNA2 motion kernels. - Follow OptiScaler's DLSS and RR preset overrides, sanitize unsupported values and select the preset matching the feature's quality mode. - Enable FSR 4 under NVIDIA GPU spoofing by exposing real AMD PCI IDs to OptiScaler and FidelityFX modules; bundle AMD's loader and upscaler. - Keep K on native kernels in engine auto mode unless HIP is selected, and fall back to CUDA for M/L when shader_float8 is unavailable. - Add native-engine K GPU timings, preset recreation harness controls and regression coverage; fix the input-wait test's glibc name clash. - Update configuration, installer guidance and release documentation, simplify the README and move gameplay videos to docs/videos.md. RDNA2 kernels remain untested on RDNA2 hardware; software matrix arithmetic was validated against WMMA on RDNA3.
