//! Export the `tish_value_*` C-ABI accessors (from `tishlang_ffi`) in the `tish` binary's dynamic
//! symbol table, so a `dlopen`'d native extension (`ffi:`) can resolve them at load time. This is
//! the **decoupled** FFI model: the extension declares the accessors `extern "C"` and does NOT link
//! `tish_core`, so there is a single value representation and no host/extension layout matching.
//! Without this flag the host's accessor symbols aren't visible to the loaded library.
