Option "--help" does not list all available options

Hello

It would be nice if the command line option "--help" would list all available options.

At least missing are:
--relay
--clipboard (even though not working for me)

Current output:

% ./sendme --help                                                        
Send a file or directory between two machines, using blake3 verified streaming.

For all subcommands, you can specify a secret key using the IROH_SECRET environment variable. If you don't, a random one will be generated.

You can also specify a port for the magicsocket. If you don't, a random one will be chosen.

Usage: sendme <COMMAND>

Commands:
  send     Send a file or directory
  receive  Receive a file or directory [aliases: recv]
  help     Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

Thanks
Stephan

Start by running sendme --help and inspect the command-line option definitions that produce its top-level help output. Ensure the --relay and --clipboard options are represented in the help text, then verify the updated output and any related CLI checks.
