Subject: [PATCH] Upgrade to Angular 19.1 with latest packages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Upgrade from Angular 17.3 to Angular 19.1
- Switch back to @angular/build with Vite bundler
- Update to latest package versions:
  - @angular/core: 19.1.0
  - TypeScript: 5.8.0
  - tslib: 2.8.1
  - zone.js: 0.15.0
- Restore application builder configuration
- Bundle size: 349.98 kB raw / 92.00 kB gzipped

Angular 19.1 includes improvements and bug fixes that may resolve
package issues in restricted environments. The latest versions should
have better compatibility and more robust dependency resolution.
