Detailed Description

Per-module timing harness for CLASS++.

Drives the lazy Cosmology pipeline one module at a time, timing each stage with a steady clock. Repeats the whole run N times (fresh Cosmology each loop) so we can report min / median / mean / stddev per module and judge which modules actually dominate the wall time – and whether a proposed optimization has any chance of moving the needle.

Usage: ./class_profiled <file.ini> [num_loops] (default num_loops = 5)

Timings are pure wall time of each GetXxxModule() call. Because the modules are memoized inside Cosmology and built in dependency order here, each call does only its own work.
