rr: Cyberpunk's extra inputs (SSS guide, colour before particles) and hardware depth

- GameFrameR/RFrameImages: DLSSD.ScreenSpaceSubsurfaceScatteringGuide (arg 264)
  and DLSSD.ColorBeforeParticles (output stage, texture 416 with its own history
  pair 384/392, zero-initialised on first use); guides array 6 -> 8
- DLSS.Use.HW.Depth: byte 980 and output byte 443 bit 24 (Cyberpunk passes the
  nonlinear depth buffer); replay's 'inverted' field becomes a bitmask
- shim: bind the two new resources, read the HW-depth flag, and accept every
  preset hint except E's 5 by mapping it to D's diamond_wallaby kernels
  (harness captures show 0x80000002/0x80000005 run preset D)
- harness: D4R_HARNESS_RR_EXTRA=particles,sss and D4R_HARNESS_RR_HW_DEPTH=1
- ptx2rr: out-of-range integer fetches return zero, matching ZLUDA's behaviour
  (the reference the stages are checked against)
- engine/rr/README: the capture findings behind the offsets

+Found on harness captures (`D4R_HARNESS_RR_EXTRA=particles,sss`, `D4R_HARNESS_RR_HW_DEPTH=1`, `D4R_RR_PRESET=N`):
+
+| what the game passes | where NGX puts it |
+|---|---|
+| `DLSSD.ScreenSpaceSubsurfaceScatteringGuide` (R16F) | encoder 0 texture 264 (its handle is the only switch) |
+| `DLSSD.ColorBeforeParticles` (RGBA16F) | output stage texture 416, flag byte 432, and a second output-size history: surface 384, read back next frame as texture 392 (linear) |
+| `DLSS.Use.HW.Depth = 1` | encoder 0 byte 980, output stage byte 443 |
+| preset hint | 5 runs preset E; every other value (0-4, 6, 0x80000002, 0x80000005) runs preset D |
+
+Integer texture fetches outside the image return zero (`fetch0`), which is what the reference does; CUDA would clamp.
+With Cyberpunk's set (hit distance, particles, subsurface guide, hardware depth) the engine's presented image is
+byte-identical to the CUDA path through the shim on the frames the harness can compare (640x360 -> 1920x1080), and
+with RE Requiem's set the network is identical on every frame (output 107-109 dB). At 1280x720 and 1920x1080 -> 4K
+without these inputs the output still falls to 43-53 dB after the first frame (the output stage's one-ulp values);
+a correctly rounded log2 there matches the capture worse than the GPU instruction does.
