// Normalizes openapi-generator output so `bun run generate` is idempotent.
//
// The typescript-axios templates emit trailing spaces on some lines and extra
// blank lines at end of file. Left alone, every regeneration produces a noisy
// whitespace diff that masks real spec/client drift. This pass strips trailing
// whitespace from every line and ends each file with exactly one newline.
//
// openapi-generator maps arrays with `uniqueItems` to `Set<T>`, but Axios
// decodes and encodes their JSON representation as arrays. Keep the generated
// type aligned with the runtime wire value.
