Architecture changes:
- Refinery created as worktree of mayor clone (shares .git)
- Polecat branches stay local (never pushed to origin)
- MRs stored as wisps in .beads-wisp/mq/ (ephemeral)
- Only main gets pushed to origin after merge
New mrqueue package for wisp-based MR storage.
Updated spawn, done, mq_submit, refinery, molecule templates.
