🔧 Fix All Knowledge Graph Relationship Rule Violations

CRITICAL FIXES: Corrected relationship types and directions to comply with AgentGraph rules from task_prompts.py and reference_based/

🚨 VIOLATIONS FIXED:

1. ❌ USES Relationships (Agent → Task)
✅ Fixed to PERFORMS (Agent → Task) in:
- kg_algorithm_sample_3.json (rel_009)
- kg_algorithm_sample_14.json (rel_009)
- kg_algorithm_sample_16.json (rel_009)
- kg_algorithm_sample_1.json (rel_009)

2. ❌ DELIVERS_TO Relationship (Output → Agent)
✅ Fixed to DELIVERS_TO (Output → Human) in:
- kg_algorithm_sample_0.json (relation_005)
- Added human_001 (Park Visitor) entity

3. ❌ Field Name Errors
✅ Fixed in kg_algorithm_sample_1.json:
- 'source_id' → 'source'
- 'target_id' → 'target'

📊 VALIDATION RESULTS:
- ✅ 47 total relationships across 6 knowledge graphs
- ✅ 0 violations remaining
- ✅ All relationship directions now comply with strict rules:
- CONSUMED_BY: Input → Agent
- PERFORMS: Agent → Task
- USES: Agent → Tool
- DELIVERS_TO: Output → Human
- All other types: Correct directions

🎯 IMPACT: Knowledge graph visualizations will now render all relationships correctly with proper entity connections.
