fix(V4B): V4.36.40 — 短路级热切换线圈死锁修复

Browse Source 
用户实测: <20µH 短路级强制断开后, 不断电换正常线圈不恢复(拨码不重启), 只能断电.
根因: 强制期 ISR 847 每5ms压 LOOP_OK=0 → vd1_task 停摆 → Origin/LPCNT 冻结在旧短路线圈值;
      recover 用 calc_freq_khz(冻结Origin,LPCNT) 判回窗永远>171k → 死锁.
修复: recover 恢复判定改 TMR3 捕获 ISR 实时 Xn (f=240000/Xn, 每振荡周期新鲜);
      换线圈后 f 回窗连续5s → 实时置档 → ISR 847 停压 LOOP_OK 自然回位 →
      主循环 0→1 沿检测自动发起 reconnect confirmed → 无车判稳门控 → Origin 判稳重建.
