Add ability to retry last request manually

### Describe the feature or problem you'd like to solve

A gesture to retry the last request when failed

### Proposed solution

_No response_

### Example prompts or workflows

_No response_

### Additional context

The CLI retries requests up to a few times depending on the error. But in the case of transient error or client network errors, it would be helpful to have a manual gesture to retry requesting the last request
