Root cause: gt done and mq submit created merge-request beads but did
not write to the .beads/mq/ directory that the refinery Engineer
polls for work.
Changes:
- done.go: Submit to mrqueue after creating MR bead
- mq_submit.go: Submit to mrqueue after creating MR bead
- mq_migrate.go: New command to migrate existing stale MR beads
- mrqueue.go: Follow beads redirects for shared queue location
The migration command allows recovery of existing stale MRs that were
never processed because they only existed as beads.
