ROM File Provider — Copilot review fixes — Addressed all Copilot review issues: replaced NSCocoaErrorDomain/NSFeatureUnsupportedError with NSFileProviderError(.unsupported) in mutation methods; added filename sanitization to strip / and : from system names and game titles; removed .allowsEvicting capability since there is no rehydration path; added allowsContentEnumerating to folder items; tightened platform guard to #if canImport(FileProvider) && (os(iOS) || os(macOS) || os(visionOS)); improved domain registration error handling; clarified visionOS support scope in comments.
