Help flag produces usage information for every command

A CLI without help text is a CLI no one can use. Users land on your tool via npx mytool or pip install, type --help out of reflex, and either see nothing or see a framework-default skeleton. They close the terminal and find a competitor. Missing descriptions also break shell autocomplete hints, man-page generation, and docs scrapers that harvest --help output. This is a user-experience failure severe enough to zero out adoption regardless of how good the underlying logic is.

Add a description to every .command(), cobra.Command, @cli.command(), or #[command] definition, and verify --help and -h produce usage text on the root command plus every subcommand. Ship descriptions in the same file the command is registered in — for example src/cli/commands/deploy.ts:

program
  .command('deploy')
  .description('Deploy the current project to production')
  .action(deploy)
