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

+"""Infer the footing rebar layers B1-B10 from the footing size (2026-10-19, read-only trial). The rules were read off the template pier (운곡교 P1):
+bars run (footing - 200) long; the dense layers (B2/B4, B6/B8) have the two end bars, one bar 200 (X-position axis) / 175 (Y) inside, then a 125 grid;
+the sparse layers (B3, B7, B1, B5) the same with a 250 grid; B9 ties sit on a 250 grid (checkerboard, half of the points); B10 hoops grow with the footing.
+The result is checked against (a) the template params (P1: must reproduce) and (b) the bar counts of the pier's own rebar schedule (independent evidence).
+usage: python tools/infer_footing_rebar.py <size_x> <size_y>   -> prints the layers; with --check <params.json> compares with that file's footing_rebar"""
