Feature Request: Session switching from inside the CLI

I know we have the --continue and --resume parameters, but it would be nice to be able to do that from the CLI, especially if you use the VSCode integration, where Cmd-Esc always starts a fresh session - this forces me to always use the terminal pane so I can --resume.
I propose a /session command which shows the last 10 sessions with IDs(permanent, generated, short), ordered by last used - then "/session a1" "/session b4" would quickly switch sessions.
