fix: GCC 16 / C++20 build failure with u8 string literals (#1685)

* fix: GCC 16 / C++20 build failure with u8 string literals (#1684)

In C++20, the `u8""` string literal prefix was changed to evaluate to `const char8_t[]` instead of `const char[]`. This caused compilation errors when these literals were implicitly converted to `std::string` or passed to functions expecting `const char*`.

This commit adds `reinterpret_cast<const char*>` around the `u8` string literals in the test suite to resolve the build errors while maintaining the intended UTF-8 semantics.

Additionally, this adds C++20 to the GitHub Actions CMake test matrix to ensure we don't regress on newer standards.

Fixes #1684

* style: run clang-format
