Bumped max_attempts from 3 to 5 — with per-system dedup and no stem
cap, the remaining dedup hits are mostly per-body collisions which
a couple extra attempts with rotated pools can escape.
Bumped --refresh default from 200 to 1000. Fewer subprocess restarts
= fewer model reloads via distrobox. KV-cache bleed risk is lower
now that the validation gauntlet is lighter.
Reverted the batch-prompt experiment — Gemma 2 2B drifts on
multi-line output; individual calls are more reliable.
