Adds a run button under every `! command` Claude suggests
Adds a ▶ run button under every ! command in Claude's replies, inline (` ! cmd ) or as a ! ` line in a code block.
A press runs the command through $SHELL -lc (ten minutes at most) and submits the command and its output as your prompt, so Claude sees it and replies.
Mods cannot enter the prompt's ! bash mode, so the command gets no terminal: interactive commands (gcloud auth login, tsh login) need to be typed with ! yourself.
