This PR is a pure linting and code cleanup effort with no functional
changes, focusing on improving code quality and consistency.
The bulk of the changes involve:
* Code Formatting: The entire codebase was reformatted after updating
our `clang-format` version.
* Compiler Warnings: Addressed `-Wsuggest-attribute` warnings from GCC
by applying `pure`, `const`, and `format` attributes where appropriate.
This helps the compiler with optimizations and bug detection.
* Code Modernization:
* Variable declarations were moved closer to their first use or into
tighter scopes.
* `memset` calls were replaced with C99 zero-initializers (`= {0}`).
* Redundant `struct` keywords, unnecessary type casts, and some
superfluous `return` statements were removed.
* CI Adjustments: The GitHub Actions workflow was updated to correctly
apply compiler flags for both GCC and Clang.
