+- **R1:** The version command now uses one standard flag-parsing path. Successful
+  help is written once to stdout, with no stderr usage, and help can short-circuit
+  trailing arguments. Non-help usage errors retain status `2`. Regression tests
+  reproduced both defects before the fix; `go test ./internal/cli ./cmd/audita`
+  passed afterward. The CLI contract reflects ordinary help behavior.
