实现告警四态状态机

solve()

Alert state machine:
  id=1 ESP-001/vibration_rms state=closed next=[]
  id=2 ESP-002/pressure state=triggered next=['acknowledged']
  id=3 RPI-001/cpu_temp state=acknowledged next=['resolving']
  id=4 ARD-001/temperature state=triggered next=['acknowledged']
  id=5 ESP-001/vibration_rms state=resolving next=['closed']
Transition validation:
  triggered->acknowledged: True PASS
  acknowledged->closed: False PASS
  resolving->closed: True PASS
