Adds gh workflow disable and gh workflow enable to the v19 gh shim as operator-gated commands, matching run cancel and preventing a failing workflow from stacking up failed runs with no way to stop it. Both verbs now record the operator audit line before forwarding to upstream gh; older manifests still refuse them as undeclared.
Confidence Score: 5/5
The PR appears safe to merge; both workflow verbs retain the existing version, operator, and audit checks.
Summary
Adds version-19 support for gh workflow disable and gh workflow enable through the existing audited operator bypass.
