Update human_validation_agent.py

INTEGRATION: Add lead_scoring_agent integration to human_validation_agent

- Import and integrate lead_scoring_agent module
- Score each lead profile at action start in process_review_action()
- Add scoring_result and enrichment_data fields to LeadReview schema
- Pass enrichment data and scoring metadata to downstream agents
- Update process_batch_review() to score all leads in batch
- Store scoring metadata with each review in history
- Export scoring information in review history JSON
- Update documentation in docstrings to reflect scoring integration
- Example batch review now demonstrates lead scoring workflow

 """Human Validation Agent Module
 
 This module provides functionality for human review and validation of leads
-that require manual intervention. It integrates with the lead queue system
-to pull leads marked with 'needs_human_review', presents batch review options,
-and handles resolution workflows.
+that require manual intervention. It integrates with:
+- Lead queue system (pulls leads marked with 'needs_human_review')
+- Lead scoring agent (scores each lead profile at action start)
+- Downstream agents (receives enrichment and scoring metadata)
 
 Key Features:
 - Pull leads with 'needs_human_review' flag from queue
+- Score each lead profile using lead_scoring_agent
 - Batch review interface with multiple resolution options
+- Pass scoring metadata and enrichment to downstream handlers
 - Schema validation for actions
 - Feedback and guardrails for invalid actions
 - Handoff to downstream queue or archival
