Escartem/SophonDownloader ? reverse-engineered prompt

Build me a simple C# command line tool that can download Mihoyo game assets using the new Sophon download method, without needing HoYoPlay. I want it to support full downloads and update downloads, so I can either grab all files for a given version or download the patch between two versions. It should work for Genshin Impact, Honkai Impact 3rd, Honkai Star Rail, and Zenless Zone Zero, and let me choose the game by its ID.

Please include support for different packages like game and the audio packs, and let me pick the output folder. I’d also like basic options for region, branch, launcher ID, platform app ID, thread count, and HTTP handles, plus a silent mode and help text. Make it feel like a practical downloader I can run from the terminal, with clear messages and sensible defaults. If you need to, look up current docs online for the download flow.
