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

+Two DXF drawings on the user's Desktop (`C:\Users\User\Desktop\`) serve as the baseline reference for 평강1교 (Pyeonggang 1 Bridge) P1 pier modeling in Rhino:
+
+- **`평강1교_일반도.dxf`** (일반도, ~884KB, 24 layers) — pier general arrangement / bearing (교량받침) drawing. Contains: 교각 일반도(1)/(2) (pier general elevation/section views), 교량받침 ELEVATION TABLE, 솔플레이트 상세 (sole plate detail), 연단거리 테이블 (edge-distance table), 기둥 단면도 A-A, 평면도/정면도. Design basis notes: KL-510 design load, fck=35MPa, fy=400MPa, 한계상태설계법 (limit state design), 도로교설계기준 (Korea Highway Bridge Design Standard), elastomeric bearing 2500kN 양방향 (bidirectional).
+- **`평강1교_.dxf`** (구조도/철근 상세도, ~4.6MB, 44 layers, 25 blocks) — pier structural rebar shop drawing. Contains 교각 구조도(1)/(2)/(3): full bar list (철근 재료표) with bar marks C1–C30(+variants), P1–P10, S1–S4, W1–W2, bar shape blocks (`CSBSHPE-A01/B00/B01/C01-C/D00/D01/G20/G57/G58/H07/H08/X12`), bar numbering blocks (`CSBNUM1`, `CSBNUM1-JEWON`), sections A-A through H-H, 주철근 조립도 (main rebar assembly, ①CYCLE/②CYCLE — matches the `1CYCLE`/`2CYCLE` layer split already used in the Rhino model), coupler (커플러) details incl. slip test note, spacer (간격재)/chair detail, tie-bar (띠철근)/cross-tie (크로스타이) spacing (C.T.C 150/300/400), shape-holding rebar notes for P8/P9/P10, rebar-rise prevention steel plate (철근올음방지철판) detail, splice-distribution note ("이음이 한 곳에 집중되지 않도록 분산").
+
+Bar diameters used: H13, H16, H19, H22, H25, H29, H32.
+
+Parsed via a Node.js DXF text-extraction script (group-code parser: layers, blocks, TEXT/MTEXT content) since no DXF library was available in the environment; UTF-8 encoded file. Use this same approach (or ezdxf if later installed) to re-extract on demand rather than re-reading raw DXF text.

+See [[project-pyeonggang1-modeling-standard]] for how this is used going forward.
