### Bug Fixes

- Fixed Jack's capsule showing empty after capture (missing getMonsterType method)
- Fixed Jack being unable to configure skills in G-key panel (missing MonsterRegistry registration)
- Fixed ECG UI cooldown display not working for Jack (isSkillOnCooldown used regular fields instead of synced fields)
- Fixed Jack being unable to use Brother Tactics (handleSkill missing brother_tactics branch)
- Fixed Jack's spawn egg showing purple-black texture (missing item model JSON file)
- Adjusted Seven's spawn egg texture crop position, moved down to show more complete head
- Fixed skill cooldown refresh delay when stage 2 combo is triggered
