feat(D03): 예상 횡단 순수 함수 — 표준 횡단 기본값 · 계획고 = 중심 지반고 · 미교차 넓힘 · 코리도 측점 꼴(PLAN 544-1)
- 새 logic/D03_PlanAnalysis_Expect.ts — 공용 computeCrossDesign + B 초기 기본(리핑암 · 산쪽 절토 · 일반 측구 · 암 경계 기본) · extendUnclosed - 새 시험 test_544_1_plan_expect.py — TS 설계선 · 절 · 성토 ㎡ = 파이썬 compute_cross_design Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

"""D03 예상 횡단(PLAN 544-1) — TS `logic/D03_PlanAnalysis_Expect.ts` 값 = 파이썬 `compute_cross_design`.

기본 = 리핑암 · 산쪽 절토(모르면 좌) · 일반 측구 · 암 경계 = config 기본 · 계획고 = 측점 중심 지반고.

미교차 = 격자로 넓힌 표본 · 넓힌 표본으로 파이썬이 다시 셈한 값과 같음 · 코리도 측점 꼴.
