hailin 911132ab3e feat(agent): upgrade to Level 3 with real RAG, Memory and Evolution integration 
## Summary
Upgrade iConsulting from Level 2 (48 points) to Level 3 (68 points) by
implementing real service-to-service integration between conversation-service
and knowledge-service.

## New Files
- knowledge-client.service.ts: HTTP client for knowledge-service APIs
- knowledge.module.ts: NestJS module for KnowledgeClientService
- AGENT_EVALUATION_REPORT.md: Agent capability evaluation report
- LEVEL3_UPGRADE_PLAN.md: Upgrade plan and completion report

## Changes

### RAG Integration
- search_knowledge tool now calls /api/v1/knowledge/retrieve
- check_off_topic tool calls /api/v1/knowledge/check-off-topic
- Results include real vector similarity search from knowledge base

### Memory Integration
- save_user_memory writes to PostgreSQL + Neo4j via knowledge-service
- collect_assessment_info saves user data to long-term memory
- generate_payment records payment intent to user memory
- New get_user_context tool retrieves user's historical memories

### Evolution Integration
- getAccumulatedExperience() fetches approved system experiences
- sendMessage() dynamically injects experiences into system prompt
- System learns from approved experiences across all conversations

## Expected Score Improvement

|------------|--------|-------|-------|
| Tool Use   | 14/20  | 18/20 | +4    |

hailin 72e67fa5d9 fix(conversation): implement proper tool loop for Claude API 
- Fix streaming JSON parsing for tool inputs by accumulating partial JSON
  and parsing only on content_block_stop
- Implement proper tool loop to continue conversation after tool execution
- Send tool results back to Claude to get final response
- Add safety limit of 10 iterations for tool loops

This fixes the issue where AI responses were truncated after using tools
like search_knowledge.
