How to write idiomatic, efficient RxJS code. Use this skill whenever the user is writing, refactoring, reviewing, or debugging code that uses RxJS — including any file that imports from 'rxjs' or 'rxjs/operators'. Trigger on mentions of observables, subscriptions, RxJS operators, or reactive streams. Even if the user doesn't say "RxJS" explicitly, activate when you see patterns like `.pipe()`, `.subscribe()`, `Observable`, `Subject`, `BehaviorSubject`, `switchMap`, `mergeMap`, or similar.
