Cyberpunk 2077 hash updater tool

Automatically updates broken Cyberpunk 2077 mangled name hashes for plugins.

DISCLAIMER: This tool is almost entirely vibecoded by ChatGPT with Codex (I had a subscription and wanted to see how it worked). The fact that it works is a miracle.

This tool relies on the IDA Domain library for binary analysis and thus requires IDA Pro to work.
