[PoC] Proposal of RBS generation method using Rack architecture

RBS generation problem

RBS is an easy language to generate code for because of its simple syntax and lack of dependencies between files. In addition, there are currently a large number of required type definitions, so code generation for RBS is considered to be highly important.

Various attempts have been made to generate RBS code, including generation from JSON files and analysis of static and dynamic Ruby code. However, each method has its advantages and disadvantages, and not all problems have been solved.
