feat: Add integration testing with real vector databases (Phase 5)
Phase 5 of optional enhancements: Integration Testing
**New Files:**
- tests/docker-compose.test.yml (Docker Compose configuration)
- Weaviate service (port 8080) with health checks
- Qdrant service (ports 6333, 6334) with persistent storage
- ChromaDB service (port 8000) with persistent storage
- Auto-restart and health monitoring for all services
- Named volumes for data persistence
- tests/test_integration_adaptors.py (695 lines)
- 6 comprehensive integration tests with pytest
- 3 test classes: TestWeaviateIntegration, TestChromaIntegration, TestQdrantIntegration
- Complete workflows: package → upload → query → verify → cleanup
- Metadata preservation tests
- Query filtering tests (ChromaDB, Qdrant)
- Graceful skipping when services unavailable
- Best-effort cleanup in all tests
- scripts/run_integration_tests.sh (executable runner)
- Beautiful terminal UI with colored output
- Automated service lifecycle management
- Health check verification for all services
- Automatic client library installation
- Commands: start, stop, test, run, logs, status, help
- Complete workflow: start → test → stop
**Test Results:**
- All 6 integration tests skip gracefully when services not running
- All 164 adaptor tests still passing
- No regressions detected
**Usage:**
# Complete workflow (start services, run tests, cleanup)
./scripts/run_integration_tests.sh
# Or manage manually
docker-compose -f tests/docker-compose.test.yml up -d
pytest tests/test_integration_adaptors.py -v -m integration
docker-compose -f tests/docker-compose.test.yml down -v
# Individual commands
./scripts/run_integration_tests.sh start # Start services only
./scripts/run_integration_tests.sh test # Run tests only
./scripts/run_integration_tests.sh stop # Stop services
./scripts/run_integration_tests.sh logs # View service logs
./scripts/run_integration_tests.sh status # Check service status
**Test Coverage:**
✓ Weaviate: Complete workflow + metadata preservation (2 tests)
✓ ChromaDB: Complete workflow + query filtering (2 tests)
✓ Qdrant: Complete workflow + payload filtering (2 tests)
**Key Features:**
• Real database integration (not mocks)
• Complete end-to-end workflows
• Metadata validation across all platforms
• Query filtering demonstrations
• Automatic cleanup (best-effort)
• Graceful degradation (skip if services unavailable)
• Health checks ensure service readiness
• Persistent storage with Docker volumes
