thosearcheryguys/club-mode ? reverse-engineered prompt

Build me a Mac app called Club Mode that helps DJs practice on Rekordbox as if they were using club gear.

I want it to work on Apple Silicon Macs running macOS 14 or later, and it should guide the user through the permissions they need. The main value is adding useful practice overlays on top of Rekordbox, like split waveforms, a way to fine tune BPM more precisely, and CDJ style phase meters that actually feel usable.

Make it feel polished and simple for a DJ to set up, then run alongside Rekordbox in Performance mode with 2 Deck Horizontal selected. If something is not supported, show clear helpful messages, especially for Rekordbox versions outside the supported range. Include a clean settings area where the user can turn Club Mode on or off and manage the required permissions. If you need to, look up current macOS app and overlay behavior docs online so the implementation is solid.
