Foundry DeFi Stablecoin CodeHawks Audit Contest

Summary

Reduce gas usage by moving to Solidity 0.8.19 or later

Vulnerability Details

In earlier releases and in the default legacy code generation, when an internal library function
or a free function accessed via a module was called only during contract creation, e.g. only
in the constructor, a copy of the function still also occurred in the contract's runtime bytecode.

This was fixed in the version 0.8.19 and later.
