/// Rust-side wrapper around a Swift class implementing the `{{ trait_name }}` plugin protocol.
///
/// The Swift instance is held via a `swift-bridge` opaque handle that retains
/// the underlying ARC reference for the lifetime of this struct. Send + Sync are
/// asserted unsafely: Swift classes used as generated plugins must be thread-safe
/// (the `Plugin` super-trait requires it), and ARC handles themselves are safe to share.

    inner: ffi::{{ box_name }},
    /// Cached `Plugin::name()` — required because the trait returns `&str` but
    /// the Swift FFI shim returns an owned `String`. Populated lazily on first access.
    name_cache: ::std::sync::OnceLock<String>,
