C++26 Brings JSON Parsing to Compile Time, Eliminating Runtime Overhead

C++26's static reflection and #embed directive enable developers to parse JSON configurations at compile time rather than runtime, eliminating startup overhead and catching configuration errors at build time instead of in production. By leveraging simdjson's compile-time parsing capabilities, developers can synthesize typed C++ objects directly into executables, transforming static configuration data into zero-cost abstractions. This approach is particularly valuable for applications with fixed configuration files, shifting verification and optimization from runtime to the build process.
