feat(D 예정노선): 거리재기 첫 점이 노선 위면 노선 따라 길이 (PLAN 600-2 · 요구 463-23)

- 새 순수 셈 logic/D03_PlanAnalysis_Measure — 같은 선 누가 차 · 갈래 고리 따라 올라가 만남 · 이어지지 않으면 곧은 거리 - 재기 겹 — 첫 누름 선 8 px · 꺾임점 12 px 안이면 노선 따라 · 굵게 그림 · 글 「노선 따라 L m · 측점 · Δh」 - Page.ts 한 줄(노선 넘김) · 새 시험 test_600_2_plan_measure Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

+TS 를 tsc 로 옮겨 node 로 돌림(서버 · 화면 없이).
