- Add Known Limitations section to DEPLOY-SUBWORKFLOWS.md
- Document UNR-01: Unraid shows "apply update" after bot updates a container
- Explain root cause: bot bypasses Unraid's XML template system
- Provide workaround: click Apply Update in Unraid (instant, image cached)
- Clarify "Check for Updates" does NOT clear badge, may create new ones
- Mark UNR-01 as complete (documented limitation with workaround)
