빌드 부산물 추적 해제와 AX Agent 대기열·composer UI 정리

- .gitignore에 bin/obj/publish 및 IDE/OS/비밀정보 패턴 추가
- Git 인덱스에서 publish 및 src 하위 bin/obj 빌드 부산물 추적을 해제하여 저장소 노이즈를 정리
- DraftQueue를 실행 대기/최근 결과 섹션과 상태 요약 pill 구조로 재정리
- composer 상단 모델/컨텍스트/프리셋 줄과 하단 작업 위치 칩 UI를 더 평평한 시각 언어로 통일
- 워크스페이스·브랜치·워크트리 패널에 공통 row 및 요약 strip을 적용해 panel UX를 정돈
- README.md와 docs/DEVELOPMENT.md, docs/AGENT_ROADMAP.md, AGENTS.md 이력을 갱신
