Describe your bug.

I ran into weird bug when type inference based on DataFrame logic didn't match between running my project in Node and in Bun-compiled binary. After digging in a little bit a found out that the datatype.variant differs in builds (which broke the following login in the function):

polarsField: { name: 'name', type: DataType(String) },

polarsField: { name: 'name', type: DataType(String2) },

It's X layers of indirection (builds/compilers/etc) to figure out why it acts like this so I guess a safer solution would be just using constant for type identities to eliminate this possibility
