flipperdevices/flipperzero-firmware ? reverse-engineered prompt

I want to build the firmware for a handheld hacking multi-tool, kind of like a "tamagotchi for hackers." The main goal is to create a portable device that can interact with various wireless protocols and access control systems.

It needs to be able to handle NFC, RFID, and Sub-GHz signals, so it can do things like read and emulate key fobs or garage door openers. It should also include an infrared feature to work as a universal remote for TVs and other devices.

The firmware should be written primarily in C, with a core OS layer that manages hardware and runs applications. Please set up the project structure to include the core system, libraries for all the different protocols, and a separate folder for applications. Make sure to create the necessary build scripts so I can easily compile the full firmware and flash it onto the device from my computer.
