Rewrite jwt-pitbul and boko-framework with modern Bux constructs

Browse Source 
- jwt-pitbul: algebraic enums, Array<String>, methods on JwtAlg,
  string interpolation, structured Result/Option error handling.
- boko-framework: StringMap<String> for headers/query/path params,
  Request/Response methods, StringBuilder, for loops, algebraic enums.
- Update READMEs and bump versions to 0.2.0.

Boko is a lightweight, multi-threaded web framework that brings FastAPI-style routing to the Bux programming language. It handles HTTP parsing, path pattern matching, query parameter extraction, and response building so you can focus on your application logic. Boko is a lightweight, multi-threaded web framework that brings FastAPI-style routing to the Bux programming language. It handles HTTP parsing, path pattern matching, query parameter extraction, and response building so you can focus on your application logic.
This version (0.2.0) is rewritten with modern Bux: `struct` methods, generic `StringMap<String>` for headers/query/path params, `for` loops, algebraic enums, `StringBuilder`, and string interpolation.
