The C# still called AsalyzeTrackPurchase, whose ObjC bridge symbol was removed in
this release, so the package would have failed to link. Both are gone now, which
means a project still calling it fails to BUILD rather than silently sending data
that cannot be deduped.

Asalyze-2.0.0.unitypackage is rebuilt from the same GUIDs as 1.3.1, so importing
it upgrades the existing assets in place instead of duplicating every script.

TrackAdRevenue, TrackEvent, SetUserId and InstallId are unchanged.
