fix(audit-meta): simplify meta-audit to section-marker check

Previous version checked for field names (weak_types, etc.)
in DSL content. That's wrong - those are bucket names that
only appear when there are findings. New version just checks
the 14 required section markers + the cross-audit-findings
count line. Skips candidate aggregates.

Meta-audit now passes clean on the 2026-06-22 audit output.
