feat(V4B): V4.36.28 — 低Q 锁死根因: 静态带回缺口 → REL_BAND_LO_MULT 180

Browse Source 
23µH/33µH 双日志 + V4.36.27 诊断字段定位 (QLO/RSM/RLN/RCN):
- 排除: Origin 漂移(129094 恒定)/g_q_lo(=1)/平滑滞后(RSM 跟随)/σ25(实测 σ1-2)
- 根因: 23µH 板停临界稳态回摆 Origin-36, 释放线 Origin-34(MULT150) 高 2 counts
  → RCN 永不累计锁死; 33µH 回摆 Origin-25 富余 9 正常
- 修正: MULT 150→180 (带回 35→41): 23µH 线 Origin-41 余 4 counts 释放;
  回滞 49-41=8 counts=4~8σ 安全; MULT200(回滞3)否决
语法0 error, 4测试全绿; spec V2.44 / devlog V2.63
