Implement two major enhancements to test generation workflow:
1. Gemini Test Enhancement (Phase 1.5)
- Add Gemini CLI analysis for comprehensive test suggestions
- Generate enriched test specifications for L1-L3 test layers
- Focus on API contracts, integration patterns, error scenarios
- Create gemini-enriched-suggestions.md as artifact
2. Planning Notes Mechanism (test-planning-notes.md)
- Similar to plan.md's planning-notes pattern
- Record Test Intent (Phase 1)
- Embed complete Gemini enrichment (Phase 1.5)
- Track consolidated test requirements
- Support N+1 context with decisions and deferred items
Implementation Details:
- Created Gemini prompt template: test-suggestions-enhancement.txt
- Enhanced test-task-generate.md with Phase 1, 1.5, 2 logic
- Gemini content embedded in planning-notes for single source of truth
- test-action-planning-agent reads both TEST_ANALYSIS_RESULTS.md and test-planning-notes.md
- Backward compatible: Phase 1.5 is optional enhancement
Benefits:
- Comprehensive test coverage (API, integration, error scenarios)
- Full traceability of test planning process
- Consolidated context in one file for easy review
- Preserved Gemini output as independent artifact
