NosCoreIO/NosCore — reverse-engineered prompt

I want a working local NosTale emulator from this repo that I can run on my own machine for learning and testing. Please get the whole thing wired up so the server, API, database, and any supporting services start cleanly, the database is created and updated, and any required game data import or parsing step is handled if this project expects that.

Make it easy for someone lightly technical to use. Add or fix whatever setup scripts, config, and docs are needed so the normal flow is basically install .NET 10, set up PostgreSQL, run the project, and know what to do next. If something only works in a specific Visual Studio version or needs preview SDK settings, spell that out clearly.

Please keep the educational and unofficial nature of the project clear in the README, and include a simple quick start and troubleshooting section for common startup issues. If anything is outdated, broken, or missing, update it and look up current docs online if you need to.
