PPT 생성 고도화 3차를 반영하고 deck planning·quality gate를 추가

- DeckPlanningService와 DeckQualityReviewService를 추가해 deck brief 정규화, consulting storyline 보강, 누락된 Executive Summary/Recommendation/Roadmap/Appendix 자동 보강, deck-level 품질 점수와 경고 계산을 지원합니다.

- PptxSkill에 audience/objective/decision_ask/storyline 파라미터를 추가하고, issue_tree/before_after/decision_matrix/risk_heatmap/benefit_waterfall/operating_model/appendix_evidence 레이아웃을 네이티브 슬라이드 타입으로 정규화한 뒤 planning summary와 quality summary를 함께 반환하도록 보강했습니다.

- pptx-creator 및 strategy-deck/board-update/pmo-steering/sales-review-deck/operating-model-deck 번들 스킬을 추가·정리하고, DeckPlanningServiceTests/DeckQualityReviewServiceTests/PptxSkillAutoRepairTests로 회귀 검증을 보강했습니다.

- README.md와 docs/DEVELOPMENT.md에 2026-04-14 21:50, 22:00 (KST) 기준 변경 이력과 검증 결과를 반영했습니다.

- 검증: dotnet build src/AxCopilot/AxCopilot.csproj -c Release -v minimal -p:OutputPath=bin\verify_ppt_phase3\ -p:IntermediateOutputPath=obj\verify_ppt_phase3\ (경고 0 / 오류 0)

- 검증: dotnet test src/AxCopilot.Tests/AxCopilot.Tests.csproj -c Release -v minimal --filter 'DeckPlanningServiceTests|DeckQualityReviewServiceTests|PptxSkillAutoRepairTests|PptxSkillConsultingDeckTests' -p:OutputPath=bin\verify_ppt_phase3_tests\ -p:IntermediateOutputPath=obj\verify_ppt_phase3_tests\ (통과 5)
