Build and Publish Mana Loop Docker Image / build-and-publish (push) Successful in 1m20s
- Add applyEnemyDefenses() pipeline: dodge → barrier → armor for ALL enemies - Add speed room + agile additive dodge (capped at 0.75, spec §4.5) - Add mage barrier recharge per tick (spec §5.2) - Add effectiveArmor support for armor_corrode debuff compatibility - Pass enemy defense context via closure (no signature changes to onDamageDealt) - Add 16 regression tests for defense mechanics - All 921 tests pass (45 test files)
