Reaction Speed Benchmark created

[Girish0902]

What does this PR do?

Adds a professional, high-precision Reaction Speed Benchmark application under Projects/Reaction Speed Benchmark/. The app tracks human cognitive processing speeds by utilizing native high-resolution performance timing interfaces (performance.now()). It features a strict five-tier workflow state machine, randomized algorithmic delay intervals to eliminate pattern anticipation, active anti-cheat event filters to catch and flag premature click violations, a dynamic running history log, and long-term peak speed caching using browser localStorage.
