Let auto-approved background shell launches join native parallel batches with read-only inspection tools. Foreground cargo/test/clippy commands remain serial barriers unless the model explicitly starts them as detached background work. Adds a per-input detached-start tool hook for exec_shell background/TTY calls and task_shell_start, keeps approval-gated detached work serial, and updates the status text for mixed read-only/background-start batches.
