Angular 19 Support

[19.0.0] — 2026-06-04

Changed

• Upgraded to Angular 19 (@angular/* 19.2.x). peerDependencies now require @angular/common
  and @angular/core ^19.0.0. Install @ngui/auto-complete@19 for Angular 19 projects.
• Migrated the library template to Angular's built-in control flow syntax (@if / @for in place of
  *ngIf / *ngFor).

Internal (development tooling only — no impact on consumers)

• Migrated ESLint from .eslintrc.json to flat config (eslint.config.js); upgraded ESLint 8 → 9 and
  switched to the unified angular-eslint and typescript-eslint packages.
• Bumped dev dependencies to the newest versions compatible with Angular 19: cypress 13 → 15,
  @cypress/schematic 2 → 4.3, eslint-plugin-cypress 3 → 6, jasmine-core + @types/jasmine 5 → 6,
  @types/node 22 → 24, karma-jasmine-html-reporter 2.1 → 2.2 (reduces npm audit from 52 to 9).
• Added unit specs for the library component and service, and replaced the stale Angular CLI boilerplate
  demo specs with working TestBed setups.

Notes

• The library remains NgModule-based in this release; the standalone migration is planned for the
  Angular 20 release.
• ESLint 10, @cypress/schematic 5, and the standalone migration are deferred to the Angular 20 release
  (they require Angular 20 / angular-eslint 20).
