Fuzzer Suite for Gno

[moul]

A fuzzer suite for Gno is needed, primarily to test GnoVM, the project's most innovative component and the one most likely to contain bugs.

While testing broader areas like transactions may also be beneficial, the main goal is to establish robust fuzzing capabilities for GnoVM.

It is important to ensure that this fuzzer functions independently for Gno while also identifying discrepancies with Go outputs.

This suite must be maintainable so that the time spent building its foundations will be reusable as GnoVM evolves.
