One can imagine the piston moving with arbitrarily slow speed.

Not sure what you mean, if the piston is NOT moving, there's no increase in
energy. If the piston IS moving, there is increase in energy - albeit the
RATE of doing work is arbitrarily low, but the time taken is increased in
the same proportion.

As Henning has implied, the energy gain by each air molecule _per collision_
is poportional to the speed of the piston, but the total number of
collisions during the compression is *inversely* proportional to the speed
of the piston.
