Claude d770469a63 Update benchmark: two-panel script with warm-up and column-count sweep ...

Previous single-panel benchmark was misleading: the first sequential run
paid one-time cache-warm-up cost (skewing n=20), and only 6 columns were
used so only 6 cores were ever active on a 16-core machine.

New two-panel design:
  Left  – vary rows with 16 fixed AB columns (shows memory-bandwidth
          saturation for large n)
  Right – vary columns with fixed rows (shows the real speedup profile:
          parallel wins when n_cols >> 1)

Also adds a warm-up pass before measurements to eliminate first-call bias.
