Subject: [PATCH] Fix bash job completion notifications leaking to terminal

Replace `{ cmd; } & disown` with `( cmd & )` subshell pattern in 4
places. The outer subshell exits immediately, making the inner
background process an orphan that bash no longer tracks, preventing
spurious "[n] Done ..." messages.

Closes #2494
