evidence: red-team OptimizerV3 full session 2026-03-27 (re-run)

Replace ghost evidence from crashed 2026-03-26 session with real
adversarial coverage data. 7 strategies tested, all HELD. Per-attack
structured data with strategy, outcome, eth_extracted, floor_held_for_attack,
delta_bps, and insight fields populated from raw session output.

Fixes #1178
