* feat: add FileIO extension for file transfer abstraction Introduce extension/fileio package with Provider/FileIO/File interfaces and a global registry, following the same pattern as extension/credential. - Add LocalFileIO default implementation with path validation and atomic writes - Wire FileIOProvider into Factory and resolve at runtime via RuntimeContext.FileIO() - Factory holds Provider (not resolved instance), deferring resolution to execution time
