fix: use CommunityAnalyzerArgs instance to prevent state leaking across calls

argparse only sets defaults when the attribute doesn't already exist on
the namespace. Using the class directly meant attributes set by one call
(e.g. analyzer="kube-linter") persisted on the class and were not reset
to None on subsequent calls without --analyzer.
