Fixed a bug in useTypingEffect where a setTimeout used for the pause delay was not being cleaned up, causing potential memory leaks and "state update on unmounted component" warnings.

Refactored the hook to manage all timing logic within a single useEffect block, ensuring the timer reference is always captured and cleared in the cleanup function.

Added src/hooks/useTypingEffect.test.ts and necessary testing dependencies (vitest, jsdom, @testing-library/react) to verify the fix and prevent regressions.
