bench: A vs B·TS gap re-test — both close the gaps, TypeSafe calibrates severity

Re-ran the previously-missed scenarios on the current build without TypeSafe (A)
and with (B). Both arms now confirm CRLF-on-Location, second-order SQLi, UNION
SQLi, blind-time, IDOR and BOLA — the chaining/skill fixes are prompt-level, not
TypeSafe-gated. TypeSafe's contribution is the severity shape: it consolidates
A's long Low tail (10) into fewer, better-justified High findings (8 vs 3) and
keeps the credential-dump BOLA at Critical via data-type grading. Artifact grid
restored to A vs B·TS columns; both run arms stored.

+
+Same gap scenarios run without TypeSafe (A) and with (B). Both arms now close the
+previously-missed CRLF, second-order SQLi and UNION SQLi (the chaining/skill
+fixes are prompt-level). TypeSafe's difference is severity shape: it consolidates
