🔧 Technical Implementation

DirtyFlagManager Integration

• 4 New Helper Functions:

  • MarkFrameDirty() - Queue individual frames
  • MarkAllFramesDirty() - Batch all frames
  • MarkFramesByUnitTypeDirty() - Queue by unit type
  • GetFrameUpdatePriority() - Smart priority assignment

• 3 Modified Update Methods:

  • UpdateAllFrames() - Batched with fallback
  • UpdateFramesByUnitType() - Deferred updates
  • SetupPerformanceLib() - DirtyFlagManager init

Smart Priority System

• CRITICAL (4): Player frame - immediate visual feedback
• HIGH (3): Target/Focus frame - responsive targeting
• MEDIUM (2): Party frames - moderate batching
• LOW (1): Raid frames - aggressive batching

Event Configuration Expansion

Added 14 new events to intelligent batching pipeline:

• 13 UNIT_SPELLCAST_* events (START, STOP, CHANNEL_START, CHANNEL_STOP, EMPOWER_START, EMPOWER_UPDATE, FAILED, INTERRUPTED, DELAYED, UPDATE, INTERRUPTIBLE, NOT_INTERRUPTIBLE)
• UNIT_AURA (batch aura events)
