What

The task-info record built for background/monitored bash tasks (local_bash) now includes a shell field, in addition to the existing command and working-directory (cwd) information. The field is passed through from the caller to reflect which shell actually executed the command.

Why

This makes it possible to see which shell ran a given background command, which is useful for debugging shell-specific behavior differences when commands are run in the background.
