ypshimandClaude Haiku 5.5 13318e9393 feat(core): rebar for 2·3주형 — shear bars per column, column bars per column (plan)
- Coping §9: C10 at each column centre (@300, k_max as for one column), C9 / C11
  outside, and the gaps between columns filled @250 from both C10 groups with the
  remaining length shared evenly (추천안, Q-K2). One column gives the T형 result.
- Column bars and couplers repeat per column (P1 230 × 2 for 2주형, × 3 for 3주형).
- Footings: each footing's bars are summed per name; the longest length governs.
- C14 is kept as the T형 layout with an RB-M01 note (per-column rule open, Q-K11).
- Tests: counts for 2주형 and 3주형; T형 unchanged; too-close columns refused.
- Not yet: the ③ shear-segment table for multi columns (still single column), the
  C14 per column, and a drawing for multi columns. Not verified in a browser.
