fix(V4B): V4.36.35 — EMA cast 根治: 有符号先除 (爆炸源)

Browse Source 
35uH V4.36.34 全绿 (13+ cycle, band_timeout 2次实战) — VEM 恒 130715 暴露玄机
根因 (C 语义实锤): g += (uint32_t)_ema_d/128; _ema_d=-10 → (uint32)(-10)=4294967286
  → /128 = +33554431/样本 → EMA 爆炸 (20260907a 10:23:03 VEM 垃圾起始=CAPVD 首破 EMA)
  V4.36.34 自愈每样本兜住(炸+重置净零)掩盖; V4.36.33 无自愈 → RLN 垃圾+假触发卡死
修: g += (uint32_t)(_ema_d / 128) 有符号先除; 自愈保留最后防线
ADR 条件修复: _t_ms 恒 2000 原永不触发 → 独立计数 5×2s=10s
