will258012/FPSCamera-Continued ? reverse-engineered prompt

Build me an updated Cities: Skylines mod that lets the player walk around the city in a first person camera view.

I want it to feel like a polished continuation of the old First Person Camera mod, with the usual camera controls, smooth movement, easy toggling on and off, and settings that make it simple to adjust how the camera behaves. Please make sure it works as a proper Workshop style mod for Cities: Skylines, and keep the dependency on Harmony in mind. If there are any details you need from the current game or modding docs, look them up online and follow the latest guidance.

Also make it friendly for players who are new to the mod, so the important controls and options are easy to understand. If possible, keep the code organized so it is easy to maintain and update later.
