"""433-4 — 곡선 R 바꿔 MC 측점이 움직임(curve:47.35 → curve:49.10).

상세 갈아끼움이 옛 MC 횡단을 이어 받음.

못박는 것
  - MC 설계(사용자 칸) 남음 · 측점 id 그대로 · added · removed 빔.
  - moves 에 MC 짝(누가거리 열쇠 칸이 따라감).
  - CURVE_NEAR_M 밖으로 간 MC = 못 이음(새 측점 · 옛 열쇠 removed).

Node 헬퍼 `helper_433_swap.cjs` 가 진짜 모듈(`B06_Section_Station_Swap.ts`)을 부름.
