stuck on processing - adding possible reset or clear command

I recently ran into issues like
- "invalid capture index"
- or i accidentally used the whole buffer for a request
- or my internet reception was bad and the request couldn't go through 100%

When either of those happens, then the "processing, please wait ... " overlay stays int the buffer as well as the gray background.
Closing the buffer and reopening does not solve this issue C-x does not either.

Anyhow in those cases something like a :ChatGPTRun clear_requests or just reset command would be useful, to basically reset the plugin and remove all overlays...

Or maybe i'am missing another fix how to do this?

Start at the :ChatGPTRun command entry point and trace the processing overlay state after invalid capture indexes, oversized buffers, or failed requests. Done means a clear/reset action removes the overlay and gray background and allows the buffer and plugin to be used again; verify behavior for each listed failure.
