feat(V4B): V4.36.19 — 低Q 释放抗抖 (平滑判释放+带回加宽)

Browse Source 
问题: 43nF/高灵敏/低Q(≤50µH) 金属板边界试探 → 触发稳定但释放点外移
发散至锁死(绿灯长亮); 开 DEBUG 打印复现不了(阻塞降采样平均抖动) = 关键旁证
根因: 释放带回 dlt_rel=23 ≈ 低Q σ(±15~25), 快值判释放(5样本)被抖断
修复(Q 分档, 高/中Q 零影响):
- rel_release_hit(): 低Q 用 g_rel_smooth(τ50ms REL_ALFA=46) 判释放
- 低Q 释放带回 ×1.5 (REL_BAND_LO_MULT=150: 23→~35)
- g_rel_smooth: IIR 后跟随/CAPVD=0 与重连归零/Car_In snap
