feat(B07-CAD): Space = Enter(오토캐드) · 빈 Enter · Space = 마지막 명령 반복(97-3)

- 캔버스 · 명령줄에서 Space(수정키 없음 · 길게 눌러 반복 아님) = Enter · 글 단계(TEXT · MTEXT · 표 칸 · 이름 등)는 띄어쓰기
- 글 단계 판정 = sequence-tool 단계 meta kind 'text'(activeToolWantsFreeText)
- 빈 입력 + 선택 도구 대기에서 키보드 Enter · Space = repeatLastCommand · 빈 우클릭은 확정만
- 한글 조합 중 Space · Shift/Ctrl+Space 무시
- 시험 ime-sink: 「L␣」 = LINE · TEXT 띄어쓰기 · 조합 중 · 수정키 · 반복 무시 · 빈 Space · Enter 반복 · 우클릭 반복 안 함
