root cdfeb5171b Add per-CU health test, selective masking, and compute verifier ...

New tools for boards with scattered harvest patterns where unlocked
CUs may be defective:

- bc250-compute-verify.sh: Heavy Vulkan correctness test (FP32 FMA,
  integer, bitwise, LDS) with per-element golden comparison
- bc250-cu-health-test.sh: Reboot-resuming 20-WGP isolation test using
  amdgpu.disable_cu. Results to /var/lib/bc250-cu-health-test/results.tsv
- bc250-cu-mask.sh: Generates selective disable_cu= config from failed
  WGPs — enables e.g. 38 of 40 CUs with bad ones masked
- cu_map.sh: Updated with --health overlay showing stock + healthy/failed

Usage:
  sudo ./scripts/bc250-cu-health-test.sh start   # full 20-WGP test
  ./scripts/bc250-cu-mask.sh --results results.tsv  # generate mask
  ./scripts/cu_map.sh --health results.tsv          # visual overlay
