- Enhanced error messages with actionable guidance
- Integrated into service factory with health checks
- Added comprehensive test infrastructure

Files Modified:
- src/cli/service/gemini_ai_service.h (added config struct)
- src/cli/service/gemini_ai_service.cc (rewritten for v1beta)
- src/cli/handlers/agent/general_commands.cc (factory update)
- docs/z3ed/LLM-IMPLEMENTATION-CHECKLIST.md (progress tracking)

Files Created:
- scripts/test_gemini_integration.sh (test suite)
- docs/z3ed/PHASE2-COMPLETE.md (implementation summary)
- docs/z3ed/LLM-PROGRESS-UPDATE.md (overall progress)

Build Status:  SUCCESS (macOS ARM64)
