/**
 * @deprecated Use `useObservableState(useObservableSelector(...))` instead (since ^8.1).
 * Will be removed in the next major version.
 *
 * React hook that selects a derived value from an observable and tracks
 * its state (value, error, complete).
 *
 * @template TType - The source value type.
 * @template TValue - The selected value type.
 * @param subject - The source observable.
 * @param selector - A function that projects each emitted value.
 * @param options - Optional initial value and equality comparator.
 * @returns An {@link ObservableStateReturnType} for the selected value.
 *
 * @example
 * ```tsx
 * // Preferred replacement:
 * const { value } = useObservableState(useObservableSelector(subject, (s) => s.name));
 * ```
