Add real-time BPM detection and display to HUD and title

Browse Source 
Implement real-time BPM (beats per minute) estimation in AudioAnalyzer by tracking beat intervals and smoothing the result. Display the current BPM in both the window title and the on-screen HUD. Update AudioFeatures to include a Bpm field. Adjust HUD layout to accommodate the new BPM information.
