feat: implement Phase 3-5 test suites for agent systems

✅ Phase 3: Decision Framework Tests
- Decision engine functionality tests
- Voting system tests (majority, weighted, unanimous)
- Consensus algorithm tests
- Agent lifecycle management tests
- Integration tests for decision processes

✅ Phase 4: Autonomous Decision Making Tests
- Autonomous decision engine tests
- Learning system tests (experience-based learning)
- Policy engine tests (compliance evaluation)
- Self-correction mechanism tests
- Goal-oriented behavior tests
- Full autonomous cycle integration tests

✅ Phase 5: Computer Vision Integration Tests
- Vision processor tests (object detection, scene analysis, OCR)
- Multi-modal integration tests
- Context integration tests
- Visual reasoning tests (spatial, temporal)
- Performance metrics tests
- End-to-end vision pipeline tests

✅ Test Infrastructure
- Comprehensive test runner for all phases
- Mock implementations for testing
- Performance testing capabilities
- Integration test coverage
- Phase-based test organization

🚀 All Phase Tests Now Implemented and Ready for Execution!
