Fix VRAM leak on quality changes and RGBA16 motion vectors; more games

- Shim: reuse VRAM interop buffers across features instead of freeing them;
  ROCm 7.2.x's hipExternalMemoryGetMappedBuffer retains its view twice, so
  freed buffers never released their memory (~130 MB per quality change)
- Bridge: close the exported fd after hipImportExternalMemory
- Shim: accept R16G16B16A16_TYPELESS motion vectors and convert 4-channel
  motion vectors to RG16F on the GPU, keeping VRAM interop (Dying Light:
  The Beast rendered black)
- Harness: D4R_HARNESS_RECREATE=N quality-change cycles,
  D4R_HARNESS_MV_RGBA16=1 motion vector format
- Supported games: TLOU, Control, Cyberpunk 2077, Rift Apart, HZD Remastered,
  Subnautica 2, Alan Wake 2, Silent Hill 2, Dying Light: The Beast; general notes
- README: GPU support section (native kernels only for gfx1101); ignore videos/

+General notes:
+
+- Select DLSS in the game's graphics settings where it is offered. OptiScaler can also feed DLSS from a game's FSR or XeSS inputs, but those are a fallback for games that hide DLSS and can ghost or show a black screen.
+- d4r supports DLSS Super Resolution only. Keep DLSS Ray Reconstruction off in games that offer it (such as Cyberpunk 2077 and Alan Wake 2); Control requests it whenever ray tracing is on and crashes.
+- Saving settings from the OptiScaler overlay ("Save INI") rewrites `OptiScaler.ini` and resets d4r's values to `auto`, including frame generation (`[FrameGen] Enabled=false`, `FGInput=nofg`, `FGOutput=nofg`) and `[Inputs] EnableDlssInputs=true`. Restore them afterwards, or keep a copy of the original file.
+
+Game-specific setup:
+
+- **The Last of Us Part I:** the game's Streamline integration crashes on boot with OptiScaler. Rename `sl.common.dll` in the game folder to `sl.common.dll.bak` and select FSR 3.1 in the game's graphics settings; OptiScaler passes it to DLSS through d4r.
+
+- **Control Ultimate Edition:** turn ray tracing off. With ray tracing on, the game requests DLSS Ray Reconstruction, which d4r does not support, and crashes when loading into gameplay.
+
+- **Cyberpunk 2077:** GE-Proton 11-3 loads Wine's own ICU libraries instead of the game's, and the game aborts at launch (`unimplemented function icuuc.dll.u_setMemoryFunctions_65`). Add `WINEDLLOVERRIDES="icuuc,icuin=n,b"` to the launch options (fixed in GE-Proton 11-4).
+
+- **Alan Wake 2:** with the game's own DLSS inputs, every model shows heavy ghosting. Set `AutoExposure=true` under `[InitFlags]` in `OptiScaler.ini` (or enable auto exposure in the OptiScaler overlay), or select FSR 3.1 in the game instead so OptiScaler passes FSR inputs to DLSS.
+
+- **Horizon Zero Dawn Remastered:** the game loads `dxgi.dll` only from the Windows system folder, so OptiScaler is never loaded under that name. Rename `dxgi.dll` to `version.dll` and add `WINEDLLOVERRIDES="version=n,b"` to the launch options. d4r's `d3d12core.dll` is still picked up from the game folder.
+
+- **Ratchet & Clank: Rift Apart:** set `Dxgi=false` in `OptiScaler.ini`. With ray tracing on, OptiScaler's DXGI spoofing crashes the game at startup on AMD GPUs; the `PROTON_FORCE_NVAPI=1` launch option already reports an NVIDIA GPU.
+
+- **Dying Light: The Beast:** use DLSS inputs; with FSR or XeSS inputs the screen stays black. The game passes its motion vectors as `R16G16B16A16_TYPELESS`, which needs a d4r build from 2026-09-28 or later (older builds reject every frame and show a black screen).
 
 Choose a model with `Model = E`, `Model = K`, or `Model = M` under `[DLSS]` in the game's `d4r/d4r.ini`. Model compatibility does not imply equal performance; see the [Townfall measurements](docs/performance.md) for measured frame rates.
