GitHub Finish-up-a-Thon Challenge

A developer turned an unfinished browser click speed tester into a polished CPS analytics app for GitHub Finish-Up-A-Thon.

The upgrade adds real-time CPS tracking, live graphs, session timers, anti-cheat filtering, and session modes.

It also fixes best-score persistence, improves localStorage reliability, and supports JSON export for results.

Desktop and mobile UX were refined, making the tool more usable for competitive performance tracking.
