fix: gt done creates MR bead instead of file-based mrqueue (gt-wtfej)

Previously gt done wrote MRs to .beads/mq/*.json files, but gt mq list
queried beads for issue_type=merge-request. These were two different
storage systems, so MRs created by gt done never showed in gt mq list.

Now gt done creates a proper MR bead with:
- issue_type: merge-request
- Description containing branch, target, source_issue, rig, worker

Also updated mq_submit.go for consistency.
