//! Tests for trait object handling in auto-derive and codegen.
//!
//! Bug: `Vec<trait Plugin>` (Windjammer syntax) is parsed as `Vec<ImplTrait("Plugin")>`,
//! but `type_contains_trait_object` only checks `Type::TraitObject`, not `Type::ImplTrait`.
//! This causes Debug/Clone to be incorrectly derived for structs with trait object fields.
