Subject: [PATCH] Fix bash job spam: use disown instead of set +m

set +m only suppresses notifications for jobs started after it runs.
Jobs that complete between prompts still trigger Done output.
Using disown removes jobs from bash job table entirely so bash
never prints completion notifications for them.
