Update main.md to document that main can use any effect with a default handler (Env, Exit, Clock, Logger, etc.), not just IO. Replace outdated Environment.getArgs() with Env.getArgs(). Add sections for accessing command line arguments and exiting the program. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
