[FEATURE] Add option to create a new session when `--resume` is passed via CLI

Problem Statement

I usually launch my claude code CLI with claude --resume command to keep using the same context. If the project already had some session, I select my latest one and continue. However if project had no sessions, I can't create one from this UI, so I have to exit and type claude again, which feels redundant and annoying.

Proposed Solution

There should be an option to create a new session when --resume is passed, as the user might want to not use any of the other sessions as well.
