… utilities Adds two new utility functions to the schematics dependency helper library: - getDependency: Allows a schematic to query a package.json and check for the existence of a dependency, returning its version and type if found. - removeDependency: Provides a schematic rule to safely remove a dependency from any of the dependency sections in a package.json.
Refactors several schematics (`application`, `library`, `service-worker`, and two migrations) to use the new, centralized dependency management utilities (`addDependency`, `removeDependency`, `getDependency`). This change migrates away from the older, class-based `dependencies.ts` helper and consolidates all dependency logic on the more robust, functional `dependency.ts` utility. This improves consistency and leverages the enhanced features of the new utilities, such as automatic and configurable installation task management.
…arative Moves the dependency information for the `application` and `library` schematics to module-level constants. This makes the `addDependenciesToPackageJson` functions in both schematics more declarative and easier to read and maintain.
