fix(ci): use require.resolve() instead of require() in smoke_test_exports [#755] (#759)

Issue #755: Node 24 was surfacing ERR_USE_AFTER_CLOSE on readline close in
non-TTY GitHub runners. The CLI loads fine — banner ("Installer v5.2.7")
prints before the close fires — but the after-close error kills the exit code,
making the job report a false positive.

The intent of smoke_test_exports is to validate that `bin/aiox.js` is reachable
through the package-exports gate, not to execute the wizard. require.resolve()
triggers the same gate (ERR_PACKAGE_PATH_NOT_EXPORTED on exports drift) without
loading the module, so the readline lifecycle never runs.

Closes #755
