fix: propagate ownPropertyOnly into Context.spawn() for {% render %}#893
Merged
Conversation
Child contexts from spawn() re-derived ownPropertyOnly from Liquid opts
only, dropping per-render RenderOptions overrides. That broke the contract
that parseAndRender(..., { ownPropertyOnly: true }) locks down a single
render, including partials loaded via {% render %}.
Add regression test matching prototype-chain leak PoC.
