Ferjaoui 3d79886178 perf: A100 probe results; disable nsys CUDA event trace when supported
Build on RHEL8 / build (push) Successful in 3m51s

Details 
- common.nsys_profile_flags(): shared nsys profile flags, adding
  --cuda-event-trace=false on nsys 2025.1+ (on by default there, it widens
  the host gaps between steps; kernel times are unchanged). nsys 2024.5
  rejects the flag, so it is detected from the help text.
- cf/run_probes.py: 3x3, 5x5, 7x7, 9x9 at 1, 4 and 8 streams.
- cf/results/A100/: Merlin7 A100 runs, f32 and f64 with lround, and f32
  with round (104e284) at 20k/2000 and 50k/3000. README lists them.

kferjaouiandClaude Opus 5.5 b7b786f423 perf: move ClusterFinderCUDA probes into perf/cf/
Build on RHEL8 / build (push) Successful in 4m1s

Details 
Make room for probes of other CUDA classes. common.py and gpu_span.py
stay in perf/ and become shared; the cluster-finder driver, traced
process, README and results move to perf/cf/.

- common.py: assert_build_fresh() takes the header list, capture_env()
  takes extra fields, results_dir() takes the probe folder.
- cf/cf_common.py: pedestal frames, n_sigma, rebuild-guard headers,
  DEVICE_PED_TYPE and the <date>_<f32|f64> results naming.
- gpu_span.py: optional kernel-name filter; tolerates an engine with no
  ops. Output without a filter is unchanged.
