Side panel follow-up prompt: accept the agent's greyed-out prompt suggestion (Claude Code) #210

Version: nebula 0.46.0 (macOS)

Problem
Claude Code shows a greyed-out suggested next prompt in its input box. In Claude Code I'd accept it by pressing right arrow + enter (or I could edit before pressing enter). The side panel follow-up prompt sender only types text and presses Enter, so I can't accept the suggestion from there. Typed text replaces the suggestion. I have to either focus the session's terminal and press the key myself, or retype something like the suggested text.

Request
2 ideas:

1. If you are able to read the suggested text then include it in the Nebula follow-up prompt window (that would allow editing it)
   or 2) Add a way to send a bare keypress, or specifically "accept suggestion", to the session from the side panel. For exemple just hitting enter with no yexy would work.

Why
I drive several sessions from the panel and rarely want to leave it. Accepting the suggestion is the most common next action, and it is the one the panel can't do.
