* Add a `reveal: always|never` field in task definitions from tasks.json , allowing to customize task terminal behavior on spawn * Ensure reveal: always reveals the terminal even if the old task is already running Release Notes: - Added a `reveal: always|never` (`always` is a default) field in task definitions from tasks.json , allowing to customize task terminal behavior on spawn --------- Co-authored-by: Piotr Osiewicz <piotr@zed.dev>
