/*
 * 905_nkname_run — execute the lib/ww nkname @test fixture under the
 * C-side `ww run` driver and assert exit 0.
 *
 * Same thin-wrapper shape as 904_tok_run / 904_ascii_run: asttest.ww
 * carries its own `export fn main()` that drives the @test fn and
 * signals which case failed via the exit code. This pins nkname's
 * if-ladder -> switch fold (every nkind + the unknown-kind fallback),
 * which the 990_selfhost wwdump diff only covers for kinds that appear
 * in its corpus.
 *
 * Unlike 904_tok_run, the fixture imports the `syntax` package, whose
 * printer references the token tkind/tokname, so the run needs
 * `-I lib/ww` to resolve the `import syntax` directory package.
