`test/lib/LibCodeGenSlow.sol` declares `pragma solidity =0.8.25` on a library file

Audit scope: whole-repo, commit 7aa85a4

Dimension 4 (code quality) · low

Location: test/lib/LibCodeGenSlow.sol:3

Problem

The convention is ^ for library and abstract files, = for concrete including
test mocks. This is the only library file under test/, and it is the only one
of the 22 pinned wrongly — the other 21 are concrete contracts, correctly =.
All three src/lib/*.sol libraries use ^0.8.25.

Proposed fix

pragma solidity ^0.8.25;
