❯ cargo run -p goose-cli session --help
Usage: goose session [OPTIONS]

Options:
  -s, --session <NAME>
          Specify a name for your chat session. When used with --resume, will resume this specific session if it exists.
....

I think we can rename the option to name instead of session since we are already in the session command group.

not sure if this is the PR but we should probably remove all the provider options in the top level since session is only configurable via --profile
