zsh: let a machine withhold node-login-shell's execute
execute runs any command as the operator account, which can become root
without a person. The operator withholds it on the control-node until a
call needs a person's approval (hq ADR 0268); the other machines keep it
for now. The setting execute (serve by default) is written into a
root-owned file the tools bundle reads at start, and anything but serve
withholds the verb, so the machine's runtime does not offer it.

// Withholding node-login-shell's `execute` on one machine (novox/hq ADR 0268). It runs any command as the
// operator account, which can become root without a person, so the operator withholds it on the
// control-node until a call to it needs a person's approval. The machine's choice is the module's
// setting `execute`, written by the mesh into a root-owned file the tools bundle reads at start; the
// bundle then registers the verb or not, so the machine's runtime does not offer it at all.
