feat(CAD): 331-1 각도 고정 <각도 → 길이 · 시퀀스 첫 점 숫자 무시

- 새 input-angle-lock — 다음 한 점만 고정 방향(동쪽 0° 반시계) · 커서 · 클릭은 고정 직선 위로 · 숫자는 그 방향 길이 · 한 점 · Esc · 새 명령이면 풂 · 커서 옆 안내 「각도 30° 고정 — 길이 입력」
- input-patterns — 숫자 음수 · .5 허용 · 각도 고정 꼴 · 점 글 해석 한 곳(parsePointText)
- Enter 해석 차례 — 자유 글 단계만 원문 먼저 → 각도 고정 → 점 · 거리 → 단계 선택지 → 명령 이름
- 선 · 시퀀스 미리보기도 고정 방향 · 시퀀스 첫 점의 거리 · 상대 좌표는 무시(도구 멈춤 · 「Error in tool actor」 없앰)
