swwayps/slsteam-moon ? reverse-engineered prompt

Build me this project so I can compile and run it on my machine, and make the setup as smooth as possible.

It looks like this is a Steam related C++ tool with extra protocol handlers, SteamStub support, and a Lua manifest importer, so please wire up whatever is needed to get a working build from a fresh clone. If anything is unclear, check the docs and look up current build instructions online if needed.

I want a clean build flow, a simple install or setup path, and enough guidance in the repo so a normal person can follow along without guessing. If there are optional diagnostics or special configuration switches, keep them working but don’t make them required. Also make sure the build scripts and docs match what the code actually does, and fix anything broken if you find it along the way.
