Detailed Description

Inline helpers for reading and writing RegisterValue through IFileSystem.

Files store values as ASCII decimal strings. These utilities wrap the open/read/write/close sequence and handle text serialization so that callers do not have to deal with byte buffers or std::from_chars directly.
