Vonor/waveterm-config ? reverse-engineered prompt

Build me a small repo for my Wave Terminal setup so I can keep the same config on macOS, Linux, and Windows.

I want it to be simple and portable, with no install script and no runtime dependencies, just commands that work with Wave’s own wsh tool. The main thing in it should be a winteriscoming theme module, based on the Winter Is Coming terminal theme, with a few variants. Make the module layout match Wave’s config folders so each part can be copied in cleanly, and document the exact install and uninstall commands in the module README.

Please also add a main README that explains how the config works, where Wave stores its config, and how to use wsh to set or clear any settings keys. Keep the whole thing cross platform and easy to understand, so I can drop it into a new machine and set it up the same way every time.
