shuka0158/FlipperPi ? reverse-engineered prompt

Build me a Raspberry Pi 5 desktop app for working with sub GHz remotes using a CC1101 radio board.

I want a simple Flipper Zero style interface that can actually listen for signals, show a frequency scan, capture a raw transmission, replay it a few times, and let me save what I found. It should also be able to recognize a few common fixed code remote types, let me enter a code by hand, and export or import Flipper style .sub files so I can move signals around easily.

Please also include a second part of the app for firmware management, where I can install Flipper firmware and launch it in an emulator from inside the same app. If real hardware is missing, it should still open in a mock mode so I can explore the UI. Make it feel like one clean hub for both real radio use and emulator use, with a friendly desktop interface and easy install on Raspberry Pi OS.
