Ember CLI TypeScript Integration

ember-cli-typescript is an Ember CLI addon designed to integrate TypeScript into Ember applications and addons by facilitating TypeScript compilation and type checking. The package is currently in "maintenance mode" as of version 5.3.0, meaning it will no longer receive active development for new features unless critical updates are required. Its core functionality has largely been absorbed into `ember-cli-babel` for TypeScript transpilation and official Ember blueprints for `tsconfig.json` generation. Developers are now encouraged to configure TypeScript directly via `ember-cli-babel` options and `@tsconfig/ember` base configurations, aligning with the official Ember TypeScript guides. It primarily focuses on build-time integration rather than providing runtime utilities, and its release cadence has become infrequent due to its maintenance status.
