🚀 Switch 2 Countdown — React Edition

Convert the vanilla‑JS timer from
https://github.com/TTPR-LaGuardia-Community-College/js-lab-switch2-countdown-ttpr
into a state‑driven React app that shows off the component life‑cycle.

---

🎯 Objectives

Goal	You will …
State	Store changing data with useState and trigger re‑renders.
Lifecycle	Start a “tick” when the component mounts, and stop it when it unmounts (useEffect).
Props	Feed the launch date as a prop instead of hard‑coding.
Declarative UI	Swap to “Switch 2 is out! 🎉” by changing state, not the DOM.
Stretch	Play a sound and/or run multiple timers without copy‑pasting logic.
