The three collect*FromPmJson collectors shared the same recursion (and the #55
depth cap) but were copy-pasted, so a future edit could diverge them. Extract a
generic collectNodes(doc, {type, map, key, lastWins, skipChildrenOfType}) and
reimplement all three on it, byte-output-identical (transclusions last-wins;
references/embeds first-wins + transclusionSource skip). Documents (not removes)
the write-only page_template_references graph and the near-duplicate client
lookup-context as tracked follow-ups, per the issue's guidance.
