feat(567-1): E03 2D 비원호 출발 셋 최솟값 · 판정 = 원호 Bishop · 비원호 Spencer · M-P 중 작은 값 · 면 확인 · 모형 끝 면 · 탐색 한계 모형 끝

- 비원호 꼭짓점 최적화를 난수 씨앗 셋으로 돌려 찾은 면 모두에서 방법별 최소(NONCIRC_STARTS 3)
- 판정 면 = 원호 Bishop · 비원호 Spencer · M-P 중 작은 값 · 비원호 < 원호 Bishop × 0.85 = surface_check · 판정 면 진입 · 진출이 모형 끝 1 m 안 = edge
- 탐색 한계 바깥 끝 = 모형 끝(요구 392 · Slide2 기본) · 설정 search_reach(model_end · 2h · m)
- 새 지킴 시험 test_567_1(원호 기본 대 촘촘 ≤ 0.5 % · 비원호 ≤ 3 % · 다출발 최소 · 한계 · 판정 칸)
- 낡은 시험 고침: ACADS 3a Spencer · ACADS 4 · M-P ACADS 4 비원호 탐색 허용 ±5 % — 다출발이 원문보다 낮은 면(약층 바닥 따라감 · 3a Spencer 1.217)을 찾음
