I have a melamine on tempered hardboard panel which is stuck to
drywall with an adhesive.

A section of the panel has been torn off, leaving a ragged and uneven
edge.

How do I cut the edge so I install a new section which will butt
against the cut edge of the panel on the wall without a noticeable
gap? (I don't have a circular-saw or a jigsaw).


You will probably have to replace the dry wall behind what ever you have
stuck to it. Use a dry wall saw to cut out the section. Dry wall is cheap
and so is the dry wall hand saw.
