Technical tradeoffs
- • Adding a virtual destructor might introduce a slight runtime overhead, but prevents memory leaks when deleting objects of derived classes through base class pointers.
- • Initializing variables upfront can improve code clarity but might add unnecessary assignments in some cases.

Fix various compiler warnings (-Wformat-diag, -Wmaybe-uninitialized, -Wdelete-non-virtual-dtor)
This PR fixes a set of compiler warnings across the diagnostics, text-art, and analyzer modules in GCC. The warnings addressed include -Wformat-diag issues, -Wmaybe-uninitialized warnings, -Wdelete-non-virtual-dtor warnings, and -Wunused-variable warnings. Fixing these warnings improves code quality and reduces the risk of potential bugs, contributing to a more robust compiler.
