Release snapshot, not a live admission decision

Generated from the checked U4 definitions fixture: 59 definitions (58 tract measures and county-only resilience). Consult the current API definitions for active/unavailable status after any revocation. All new measures remain outside annex exports in U4.

Decimal strings retain the stated precision. Direction is the default for the overlap, not a clinical or policy judgment. Publisher field names describe lineage; they are not extra exported values.
