The talibs do have some large crudely-modified drones (originally mainly meant for farming) so it could be their own.
I doubt it's a US drone.
It could be a Pakistani drone, but other than for intelligence purposes, I don't see why it would be there.
[Edit]: thinking about it, it's probably for intelligence purposes, and a clear threat. Panjshir is where the NRF is based, and Pakistan recently hosted a bunch of opposition Afghan leaders. Its basically saying, "keep supporting the taliban, and you lose north Afghanistan again".
