The EC2 profiling scripts under notebooks/astrasim2_correlation/correlation/
now live in their own repo (rengzhengcodes/aws-gpu-profiler), generalized
from an nccl-tests-only orchestrator into a manifest-driven GPU profiler.
Wire it in as a submodule at the same path, tracking the
profiling-data-20260904 branch, which carries the 2026-09-04 8x H100
all-to-all sweep (run correl-20260904-154601) that the notebook reads.

Notebook: read empirical CSVs from correlation/data (inside the submodule)
with the repo-root fallback, cite the aws-gpu-profiler run command instead
of orchestrate.py, and re-execute in place. Fit unchanged: alpha 74.23 us,
BW_eff 339.5 GB/s, R^2 0.9996.
