v0.4.0

The SuperMD update!

With this release Zine is now at a point where the development experience is representative of what the final product will look like.

Error messages need to be improved and a lot of developer tooling is still missing, so take that into account, but the core authoring process is now mostly there.

Zine is also now featureful enough to begin the porting process for the official Zig website!
