Schema Evolution: - Preserve version info in type resolution (Type::Versioned) - Track versioned type declarations in typechecker - Detect version mismatches at compile time (@v1 vs @v2 errors) - Support @v2+ (at least) and @latest version constraints - Store migrations for future auto-migration support - Fix let bindings to preserve declared type annotations HTTP Server Effect: - Add HttpServer effect with listen, accept, respond, respondWithHeaders, stop - Implement blocking request handling via tiny_http - Request record includes method, path, body, headers - Add http_server.lux example with routing via pattern matching - Add type-checking test for HttpServer effect Tests: 222 passing (up from 217) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
