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

+description: Standing Rhino/Grasshopper conventions for extracting sections and laying out 2D drawings — numbered method options plus always-follow layout/dimension/deletion rules

+**Section extraction method convention** — when the user asks for a section by number, it means:
+- **"1번"** = manual method — extract curves via BrepPlane, place dimensions/labels by hand into a manually-built 2D box/frame
+- **"2번"** = Rhino native ClippingSections + ClippingDrawings — live-linked to the 3D model, refreshed via `UpdateClippingDrawings`
+- **"3번"** = a ClippingPlane object cutting the section visually directly on the 3D model (no 2D curve extraction)
+
+**Always-follow rules for section/drawing work:**
+- Sections always go in the **middle cell** of a 3-split A1 frame box.
+- ClippingDrawings' auto-generated black name text dots (e.g. "AA", "BB") always get moved **outside** the drawing box.
+- **Always ask the user before deleting any object in Rhino.**
+- Two-tier dimension convention: the 2nd-tier (outer/total) dimension line sits 1000 units away from the 1st tier; only the leg segment below the arrow extends (add a stub manually below the bottom point, length = 1500, i.e. 15 at 1:1 print scale); arrow position and the length protruding above always stay as they currently are — never change those.
+
+**Why:** these are standing preferences the user set for prior P1 section-drawing work (captured in [[reference-notes-md]]) so that repeated requests ("2번으로 뽑아줘" etc.) and drawing layout stay consistent without re-explaining each time.
+
+**How to apply:** apply these rules by default on any Rhino section/drawing task in this project (and likely future pier projects per [[project-pyeonggang1-modeling-standard]]), and treat "before deleting, always ask" as a hard rule regardless of project.
