Role and rig beads are reference metadata that should never be closed
or appear as actionable work. They are similar to agent beads which
are already excluded.
- Add 'role' and 'rig' to the issue type exclusion list in GetReadyWork
- Update comments to document the excluded types
Fixes confusion where role/rig beads appeared in bd ready output,
leading agents to try to close them as regular work items.
