// Post-link callback registration. The compiler invokes `post_link`
// after `target.link()` returns (sx build). Under `sx run` (JIT) the
// callback is registered but never invoked because there's no link
// phase — so the only thing this example prints under the test
// runner is `runtime main`. The post-link path is exercised via
// `sx build` separately.
