Given an event on any venue, find the corresponding event on every
other venue and map all child markets across them. Instead of matching
one market at a time, this returns the full cross-venue mapping in a
single call.
An Event is the parent container — it holds
multiple Markets, each with their own Outcomes. Event matching maps the
entire tree across venues.
