Merge main into feat/extend-models-support

Resolved conflicts:
- feature_list.json: Merged all features from both branches
- feature-loader.js: Included both model/thinkingLevel and error fields
- board-view.tsx: Merged model/thinkingLevel and error fields, kept currentProject check
- settings-view.tsx: Merged CLI status checks with navigation/scroll code
- app-store.ts: Included both model/thinkingLevel and error fields in Feature interface

Fixed linting errors in settings-view.tsx
