* 🚑 Drop invoke_* glue checks from staging CI
The .github backport from develop added check-no-invoke-v to WASM and
Exporter CI, but staging still ships glue that uses invoke_* wrappers.
Remove those steps (and the WASM production build only used by the
check) so staging CI matches the binary it builds.
* 🔧 Disable credential persistence in commit-checker checkout
zizmor fails CI: Workflows when actions/checkout omits
persist-credentials: false. Match the rest of the workflows.
