chore(spec): regenerate protocol.mdx after the merge

Discharges the `os-regen-pending` deferral the merge driver recorded. The merge
brought an `enableOnInstall` description that git's textual merge dropped from
the generated page; only a regeneration on the committed merge restores it,
which is why the driver defers instead of trusting the text merge.

Not this card's content — regenerated, never hand-edited.
