// Helper — call the internal parse function.
// `BedrockStatus::parse` is `pub(crate)` so we access it through the models
// re-export. If it is not accessible directly in integration tests, we go
// through `ServerData::Bedrock` by constructing a fake UDP response via the
// public `BedrockStatus` struct fields — but since `parse` is needed for the
// roundtrip, we expose it via a thin test shim in models.
//
// For now we call it through `rust_mc_status::models::BedrockStatus` which
// is re-exported as `pub` from models/mod.rs.
