docs: record the audit of the rewritten CKA solutions

./ksim audit ran the 105 CKA solutions rewritten in 2026.10.27.1 on
v1.37, each on a host of its own, as the solution shows it, with every
edit by hand done by its script. All 105 seed cleanly, score nothing
untouched and reach full marks.

Add that to the README's audit record, which said 80 tasks were proven
by the solution as a drill shows it - true of the solutions before the
rewrite. No task's setup or checks have changed since the audit of
2026-10-19, nor have the other 42 solutions.
