/**
 * cli.ts — thin argv-parsing bin. Parses process.argv into the options
 * objects index.ts's API expects, calls that API, formats the result
 * (format.ts), and prints — this file is the ONLY place in the package that
 * calls console.log/console.error/process.exit(code) (process.exitCode is
 * used, not process.exit(), so a caller that imports runCli() programmatically
 * doesn't get its own process killed).
 *
 * Deliberately thin: the future `flair bench` subcommand (see README
 * "Library use") is expected to import index.ts's runBenchmark()/recommend()
 * directly and do its own argv parsing / rendering inside the main `flair`
 * CLI's existing command tree, not shell out to this file.
