/// Forces the FFI crate's compiled object code into this crate's staticlib output.
///
/// The generated Swift service API code calls FFI `#[no_mangle] extern "C"`
/// functions directly via `@_silgen_name` declarations that are invisible to
/// this crate's own Rust dependency graph — nothing in `alef`-emitted Rust
/// source here ever calls into the FFI crate. A Rust `staticlib` only bundles
/// the compiled object code of upstream Rust dependencies that are actually
/// "used"; an entirely unreferenced dependency is dropped outright, so
/// without this reference the FFI crate's exports would be absent from the
/// shipped `.a`, leaving consumers with undefined symbols at link time unless
/// they separately link the FFI archive. Referencing exactly one FFI symbol
/// is sufficient: once the crate is "used", cargo folds ALL of its compiled
/// object code — every exported C ABI function, regardless of which codegen
/// unit it lands in — into this crate's `.a`, making the shipped static
/// library self-contained.
