docs(divergences): correct ledger after adversarial re-audit (#138)

Re-verified every ledger entry against Ink v7.0.4. Fixes: MI5 (remove false
"residual false-child divergence", verified by running Ink), MI3 (Model-Implied
-> Intentional), VI2 (-> Non-Behavioral), VI3 (-> Intentional), and an
error-overview test comment (Ink renders blank error.message, not String(value)).
ID4 verified accurate and left unchanged.
