Replace the cross-entity JOIN in
DetectedTrackers.LoadCommonThirdPartyIDByDomainMatch with two
idiomatic coredata calls: LoadInitiatorDomainsByTrackerPatternID
on DetectedTrackers, then a new CommonThirdPartyDomains.Load with
a CommonThirdPartyDomainFilter. Each entity now queries only its
own table, and the caller orchestrates the lookup.
Document the Load vs LoadAll naming convention and the no
cross-entity JOINs rule in contrib/claude/coredata.md.
