Remove useEffect-based sync of _pluginInstallLocked/_dimmed in workflow nodes to avoid render-update loops.\n\nMove plugin-missing checks to pure utilities and use them in checklist.\nOptimize node installation hooks by enabling only relevant queries and narrowing memo dependencies.
Detect uninstalled model plugins for LLM nodes in the checklist and
publish-gate. Migrate ChecklistItem.errorMessage to errorMessages[]
so a single node can surface multiple validation issues at once.
- Extract shared extractPluginId utility for checklist and prompt editor
- Build installed-plugin Set (O(1) lookup) from ProviderContext
- Remove short-circuit between checkValid and variable validation
- Sync the same check into handleCheckBeforePublish
- Adapt node-group, use-last-run, and test assertions
