Mainly because "sorting_diagnostic_consumer" is legacy, since `SortingDiagnosticConsumer` became `SortingConsumer`. Also better reflecting contents of these files. Where I'm not renaming, I'm less positive about dropping "diagnostics" from "file_diagnostics" and "null_diagnostics" (which contain both a consumer and emitter, and "null.h" seems like poor naming), so not doing that here. Also "diagnostic.h" contains `struct Diagnostic`, so is a decent fit. Assisted-by: Google Antigravity with Gemini 3 Flash
