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

Many features were documented as "missing" or "planned" but are actually
working: generics, string interpolation, File/HTTP/Random/Time effects,
JSON parsing, module system, and JIT CLI integration.
Updated IMPLEMENTATION_PLAN.md, OVERVIEW.md with accurate status.
Added ROADMAP.md (use-case-targeted) and LANGUAGE_COMPARISON.md.
