chore(rebar): Pier_T_rebar 작업 폴더 초기 구성 및 외부 의존 파일 통합

- Code\rebar_pipeline, review_pipeline, pier-program을 정션에서 실제 폴더로 전환
- Code\rhino_mcp 및 CLAUDE_rhino배경.md 추가, .mcp.json은 PYTHONPATH로 새 위치 사용
- pier-program 내부 .git 제거(이력은 backup\pier-program_20261028.bundle에 보관)
- worktree 가이드 반영(CLAUDE.local.md, HANDOFF.md)
- D:\Rhino-MCP 경로 참조를 새 위치로 치환

+"""Colour rebar pipe solids by nominal diameter (run inside Rhino 8 via runner after the rebar stages).
+
+Globals: PARAMS_PATH. Ported from Code/교각모델링/apply_rebar_colors.py (Ungok P1, model v0.1.09).
+
+Rule (context-migration/디자인지침_경로.md, R8 criteria 2026-10-07): same diameter -> same colour
+regardless of steel grade (S = SD500, H = SD400). Centrelines keep their layer colour.
+Prints a check: per-diameter object count and colour, and any pipe whose colour does not match.
