Subject: [PATCH] fix(ci): release-candidate restores the web Wasm engine
 before its root build

Release run 42296982894: resolve ran a root `pnpm build` with no web Wasm engine, examples/spell-lab
(default engine) stopped at TN_WASM_ENGINE_MISSING, and ship published nothing for 0.3.12. A
ci-structure test now requires native-engine-wasm before every root `pnpm build` in any workflow.
