- Fix string interpolation issues: escape curly braces with \{ and \}
since unescaped { triggers string interpolation
- Fix effectful function invocation: use "let _ = run main() with {}"
instead of bare "main()" calls
- Use inline record types instead of type aliases (structural typing)
- Fix flake.nix to show build progress instead of suppressing output
