docs(diagnosing-superpowers): ship a scrubbed creation log; full record kept privately

The shipped CREATION-LOG.md quoted private repository names, issue and PR
numbers in those repos, memory-file names, and verbatim human-prompt text
from the fixture sessions. This repo is public.

The full 5,972-line record moves out of the tree and stays on the
maintainer's machine. What ships is the measurement: the method, the
scenarios with fixtures described by characteristic rather than by path,
the RED baseline results and the rationalizations the Red Flags table was
written from, the per-version table, the micro-tests with per-rep
verdicts, the four refactor rounds, a Red Flags provenance list, and the
end-to-end run.

Also surfaces the reliability finding in a Status block at the top: three
runs of scenario 12 on the same fixture and problem statement produced
three materially different substantive answers, all of which passed,
because the criteria test completeness and citation rather than
agreement. The spec now says so under Out of scope for v1, and its
report-path typo is fixed.
