Pull Request

🤨 Rationale

Part of the work for AzDO feature 3051218

👩‍💻 Implementation

• Updated to TypeScript 5.8.3
• Updated Angular dependencies to 19.2.17
• Updated to Angular-19-compatible eslint-config-angular version 11
• Updated forked Angular files in packages/angular-workspace/nimble-angular/thirdparty
• Fixed issue with direct import of @angular/localization/init from label provider directives, which would prevent nimble-angular from working with compile-time translation. Angular does not have great support (1, 2) for using $localize in a library, but resolved via:
  • Removed imports from the three label provider files
  • Added polyfills: "@angular/localize/init" to configuration for example app and tests.
  • Added @angular/localize to types array in tsconfig files.
• Default output path for built application changed to dist/browser subdirectory (from root dist folder), so had to add explicit outputPath configuration for the example app (to remove the intermediate directory) to keep the Lighthouse tests and the link on the Nimble site working correctly.
• Removed suppressions for @angular-eslint/no-host-metadata-property, which no longer exists.
• Various configuration changes from automatic migration

🧪 Testing

Automated tests pass. Built SystemLinkShared libraries against updated packages, and extracted localizable strings to ensure all were still captured.

✅ Checklist

• I have updated the project documentation to reflect my changes or determined no changes are needed.

I tried out the Angular example app in the storybook build and didn't see any issues.
