feat!: Split Inkay into a module and a plugin

This is necessary for a future Aroma feature. This also makes more clear
the immutability of the patches that Pretendo requires, since they
cannot be reverted easily.

All patching code is now managed inside the module, which the plugin
triggers by calling an exported function from it. The WWP reset code
remains within the plugin as it isn't strictly tied to the patches.
