Replace Mono.Options OptionSet command-line parsing with System.CommandLine RootCommand/Option<T>/Argument<T> pattern across all 6 projects: - ConsoleReferenceServer: Use SetAction with async handler, options defined as Option<T> instances, env var merging via MergeEnvironmentArgs - ConsoleReferenceClient: Same pattern with Argument<string> for server URL - ConsoleReferenceSubscriber: Inline SetAction handler replaces OptionSet - ConsoleReferencePublisher: Same pattern as Subscriber - Fuzz.Tools: Same pattern with playback/testcases/stacktrace options - MonoReferenceServer: Use centrally managed package version System.CommandLine provides automatic --help/-h/-? handling, automatic --version support, and better error messages for invalid arguments.
