docs(claude): use full n=4 measured range in Excalidraw worked example

Best run 0 Read/3 cg/76s; typical ~1 Read/~4 cg; occasional over-drill outlier.
Report the range, not a single run — run-to-run variance is large.

+Numbers are n=4 unhooked runs of the same prompt; **best run 0 Read / 3 codegraph / 76s**, typical ~1 Read / ~4 codegraph / ~78s, with an occasional over-drill outlier (10 codegraph / 2 Read / 112s). Run-to-run variance is large — that's expected; report the range, never a single run.
