Module scoring 

Multi-factor gap priority scoring with BinaryHeap

Computes priority scores for knowledge gaps based on:

• Criticality (High/Medium/Low)
• Dependency depth (deeper = higher priority)
• Evidence strength (less evidence = higher priority)
• Age (older = higher priority, capped at 30 days)
