You are making such a hash of some simple concepts.

Mammals have very good teeth that damage the seeds and they have a longer digestive transit time. Birds don’t chew the seeds and they pass rapidly through their guts.

Fruits that are eaten by mammals produce fewer offspring than fruits that are eaten by birds.

Mammals are sensitive to capsaicin, birds are not.

There is natural variation between individual plants. Some will be hotter than others. Hotter individuals have a natural advantage in breeding because they are less likely to have their seeds eaten by mammals. Therefore they have greater numbers of offspring therefore hotter individuals are selected for.

There is no intent, its natural selection.
