Chat - Page-Level AI Assistant: update from main and migrate from SystemJS by dmlvr · Pull Request #35572 · DevExpress/DevExtreme

dmlvr · 2026-10-08T15:26:34Z

Fixes the failing CI checks in #35545.

Merges main into the feature branch (it was behind: main removed SystemJS from demos and the ReactJs/**/*.html prettier override).
Migrates the Page-Level AI Assistant demo index.html files (Angular, React, ReactJs, Vue) to the bundled format and removes modulePrefix from the Angular components.
