Add an intermediate "awaiting confirmation" status before a task auto-transitions to Completed

When a background task/job finishes processing in the terminal, it immediately flips to "Completed" status. In a busy terminal with multiple concurrent tasks, a task that just silently jumps to "Completed" is easy to miss/lose track of among other output.

Feature request: insert an intermediate status (e.g. "Awaiting confirmation" / "Needs review") between "processing finished" and "Completed", so the user has a clear, visible checkpoint to notice and acknowledge the result before it's marked fully done — rather than it blending into a stream of already-completed tasks.
