Angular 19 - Component AppComponent is standalone, and cannot be declared in an NgModule

The error "Component AppComponent is standalone, and cannot be declared in an NgModule" signifies a fundamental shift in Angular's component architecture, starting with Angular v15 and becoming more prevalent in v19. Standalone components are designed to be self-contained, eliminating the need for declaration within an `NgModule`. This means you cannot list a standalone component in the `declarations` array of any `NgModule`. Instead, standalone components import other standalone components, directives, or pipes directly within their `imports` array. This approach simplifies application structure, reduces boilerplate, and promotes better code organization by making components more portable and less dependent on module boundaries.
