LM2596 and other DC-DC converters why oscillate if the output capacitor ESR value is too low?

I would like to make a low-battery cut-off ciruit with a P-MOSFET. How can I modify this circuit to be good?
Can you help me with a schematic?

Thank you. Its new for me. When switch turned off why LM358 GND pin rises to +12V?

How can I modify this circuit to if once the battery turned off, never turn on again or turn only when min. ~0.5V increased?
How got you the value 3.15V and 2.65V? For example if 10k and 500k how can I calculate it?

Thank you. It seems good. How can I calcutale when the LM1 go high again? Which voltage? | Once the LM1 output go low, will it go high again or never?
