Description

We have some pretty gross types that we have to initialize in places, especially when it comes to the PTE solvers.

Instead of explicitly declaring these types, it may be more useful to implement CTAD in various places so that the class template can be automatically deduced from the constructor arguments.

Contributor guide

Research direction
Find all variable declarations where the type can be deduced from the initializer. Replace explicit type with `auto` or use CTAD for class templates. Ensure deduction guides exist for constructors. Run the test suite to verify.
