Now that the project targets C++23, use the standard library's std::expected instead of the vendored tl::expected polyfill: - tl::expected -> std::expected, tl::unexpected/tl::make_unexpected -> std::unexpected - .map()/.map_error() -> .transform()/.transform_error() - #include <expected.hpp> -> #include <expected>, grouped with std headers - Remove 3rdParty/tl/expected.hpp (the tl target remains for function_ref.hpp) Co-Authored-By: Claude Fable 5 <[email protected]>
