ayo 162bbd77c8 shim: adaptive marker polling, opt-in GPU-side input wait/completion and RGBA8 output 
- [Interop] MarkerPollUs = auto is the new default: the input-marker wait learns when
  each feature's inputs become ready, sleeps in <=200 us chunks, yields near the
  prediction and backs off when late (d4r_input_wait.h); a number keeps fixed pacing
  (0 yields). d4r_config.py no longer exports 200 when the key is unset

- D4R_SHIM_GPU_INPUT_WAIT=1 (experimental, split VRAM, age 0): NGX's null stream
  waits on a coherent Vulkan word imported into HIP (d4rStreamWaitValue32Eq) instead
  of CPU polling. The original readback marker stays the authority; a CPU watchdog
  releases discarded lists and timeouts. Denoiser, verify, capture and dilation
  frames keep the CPU wait

- D4R_SHIM_GPU_COMPLETION=1 (needs GPU_INPUT_WAIT): the bridge writes a completion
  word right after the native output kernel (d4rNgxWriteValue32), and the game's queue
  polls it with a bounded compute wait (kernels/support/vulkan_wait.comp), replacing
  the split list's CPU timeline signal. frame_retired writes the same word on every
  failure path

- D4R_SHIM_NATIVE_COMPLETION=1: a null-stream callback in the bridge signals the
  split timeline (d4rNgxTimeline*); D4rFrameCompletion::can_signal only releases the
  oldest outstanding frame

- RGBA8 output: tex_common.h adds an 'R4' redirect tag, so K's native output kernel
  stores packed RGBA8 directly (D4R_SHIM_OUTPUT_RGBA8=1, checked against the kernel
  manifest by d4rOutputKernelRgba8). Host packing handles RGBA8 too.
  patches/vkd3d-proton/0004 (VKD3D_D4R_LINEAR_RGBA8=WxH) makes such outputs linear and
  exportable so the result can be written in place

- D4R_SHIM_FUSE_RGBA8_INPUT=1: one Vulkan pass converts and copies RGBA8 color input
  (vulkan_read.comp mode 5 matches the blit's toward-zero halves, plus a row stride)

- profiling: thread CPU time from the Unix bridge (Wine's GetThreadTimes ticks at
  10 ms); game-queue D3D12 timestamps (vk_input/vk_dlss_wait/vk_output/vk_total);
  gpu_eval split into input_gpu_wait and dlss_gpu; D4R_PROFILE_GPU_EVENTS,
  _TIMESTAMPS, _LOG and _CPU_TIME=0 switch off individual parts for bisection

- bridge: D4R_NGX_STREAM_PRIORITY=high|normal runs NGX on a priority stream
  (off by default; no gain measured)

- release_feature: a feature already marked retiring by a failed drain can still
  be released normally

- harness: RGBA8 with motion and jitter scenes (re-quantized each frame),
  D4R_HARNESS_RGBA8_RAMP, D4R_HARNESS_THRASH_MB to evict L2/Infinity Cache before
  each evaluation

- kernels/native: in_hoist.py and split_output_paths.py (opt-in scheduling
  experiments); scripts/build_k_ldr_output.sh builds K's LDR output with an
  optional D4R_LDR_OUTPUT_MAX_VGPR cap

- tests: test_input_wait.py and test_latency_optimizations.py; MarkerPollUs and
  frame-completion tests updated
