[FEATURE]: command to continue session inference

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

Sometimes reasons like:

• user interrupts,
• free limit exhaustion, or
• premature model inference termination (most prevalent)

Cause the session to hang and wait for user input. However, logically there is no additional user interaction necessary (the session was mid-task and simply has not finished)

I think it would be very useful to have a command (/...) that would instruct the model to simply start the inference call again, without having to send another prompt.

/continue and /resume are already taken (aliases for routing to the most recent session), so I propose to either repurpose 1 of them (remove redundancy) (would lean more to /continue), or a new /... command that would fit semantically to this purpose
