- Updated `data/cards.json` to change triggers for Bloodrage from `passive` to `preBattle`, and renamed Strike skills to Legion with `preBattle` trigger.
- Refactored `CombatEngine.js` and `SkillProcessor.js`:
- Removed ad-hoc event pushing for Bloodrage during the attack phase.
- Moved Legion and Bloodrage processing into the `_preBattlePhase` to generate buff events that are animated before combat resolves.
- Added logic to track temporary buffs in `_tempBuffs` for Legion.
- Enhanced `BattleScene.js`:
- Implemented new animations for Legion (cycling flexing arm sprite) and Bloodrage (pulsing red sprite).
- Added support for restoring and re-applying Drain effects during the pre-battle display phase to ensure correct visual state before animation.
- Updated sound loading in `BootScene.js` for new `legion` and `bloodrage` effects.
