Persist a short note to the top of the user's Clipper clipboard-history list without touching the system clipboard. Use when you want to leave the user a durable, glanceable note, reminder, summary, or hand-off message they will see in their Clipper app — e.g. "remember to rotate the key", a TODO, a link, or a snippet you produced for them to copy later.

Pause a shell script or CI step until a duration elapses and/or events are satisfied (process alive/gone, file exists/absent), with an optional deadline that turns the wait into a hard timeout.
