docs: Remove all pycli references and obsolete Python backend documentation

Changes:
- Removed pycli backend references from README.md
- Removed pycli backend references from README_CN.md
- Deleted obsolete python-tools-strategy.md file
- Updated project structure documentation to reflect current scripts
- Replaced Python backend section with enhanced test generation features

This cleanup ensures documentation accurately reflects the current system
without the removed Python CLI components.

-### 🐍 **Python-Powered Backend (`pycli`)**
-Advanced semantic context discovery system:
-
-```bash
-# Hierarchical vector database support
-pycli --semantic-search "authentication patterns"
-
-# Auto-detects parent directory vector DB
-pycli --context-discovery --inherit-parent
-
-# Intelligent file relevance scoring
-pycli --analyze-relevance "jwt token validation"
-```
+### 🧪 **Automated Test Generation**
+Comprehensive test workflow creation:
+- **Implementation Analysis**: Scans completed IMPL-* tasks for test requirements
+- **Multi-layered Testing**: Unit, Integration, E2E, Performance, Security tests
+- **Agent Assignment**: Specialized test agents for different test types
+- **Dependency Mapping**: Test execution follows implementation dependency chains
