feat(B05 추천 횡단 토공): CrossEarth 새 파일 · 표준 횡단면 = 저장 패널값 · 판 8 + 소스 지문 · [재계산] 서버 · with_profile 저장 (420)

- 새 B05_Profile_Engine_RouteInitial_CrossEarth.py — cross_earthwork(line, chainages, design_z, terrain, standard) · cross_earthwork_delta(before, after, changed_chainages, …) · attach_cross_earth(결과 표 절 · 성 = 횡단)
- 균형 종단 · 횡단 토공 표준 횡단면 = 프로젝트 저장 패널값(추천 · [적용] 둘 다) · generate_initial_route standard 인자
- 저장본 ALGO_VERSION 8 · 엔진 소스 지문 열쇠 · 표준 횡단면 열쇠 · 옛 판 · 옛 지문 미리 셈 때 지움
- 요청 recompute — 묶음 잠금 안에서 이 묶음 저장본 · _POOLS 버리고 새로 셈 · 저장본 request 엔 안 적힘
- initial_choice.json with_profile([적용] 「종단 반영」) · 미리 셈 다섯 갈래 종단 켬
- 시험 420_1 새로 · 224_3 · 364_4 · route_initial 고쳐 씀
