Feature Request: Allow passing conversation name as the second argument for /new command Description

What variant of Codex are you using?

cli

What feature would you like to see?

I hope the /new command in Codex CLI can support a second parameter.
For example, when I run /new Add User, the newly created conversation will be automatically named Add User, which behaves the same as creating a new chat via /new first and then executing /rename Add User manually.

Use Case
This would eliminate the extra step of running a separate /rename command right after starting a new conversation, improving workflow efficiency when creating topic-specific chats.
Expected Behavior

• Input: /new [custom_conversation_name]
• Outcome: Creates a brand-new conversation and directly assigns the given name to it in one single command.
