코워크 문서 생성 기본 포맷 편향 완화

문서 생성 도구가 인자 없이 호출될 때 html/professional로 고정되던 기본값을 제거했습니다.

DocumentPlannerTool과 DocumentAssemblerTool이 설정값(DefaultOutputFormat, DefaultMood), 문서 유형, 요청 키워드를 함께 보고 docx/html/markdown 및 corporate/dashboard/minimal/creative/professional 무드를 자동 선택하도록 조정했습니다.

README와 DEVELOPMENT 문서에 변경 배경과 검증 결과를 반영했고, dotnet build 기준 경고 0 오류 0을 확인했습니다.
