Alias `--resume` to `resume`

What variant of Codex are you using?

CLI

What feature would you like to see?

Silly suggestion, but if you type code --resume Codex CLI just gets confused.

> codex --resume
error: unexpected argument '--resume' found

  tip: a similar argument exists: '--remote'

Usage: codex [OPTIONS] [PROMPT]
       codex [OPTIONS] <COMMAND> [ARGS]

For more information, try '--help'.
