This replaces usages of `llvm::fs` and string manipulation with `std::filesystem`, also replacing `std::string` with `std::filesystem::path` where it made sense. Moreover MD5 hashing used in macOS file remapping was replaced by SHA256 hashing using a small header-only SHA256 C++ library with an MIT license, https://github.com/okdshin/PicoSHA2. File contents hashing was relocated to the newly created `file` library for later planned reuse.
