#3647 test: Add more parent-child snapshots Pull request opened by edgarrmondragon Summary by Sourcery Add new snapshot-based tests to validate various parent-child stream behaviors in tap synchronization. Tests: • Add regression test ensuring child streams with empty state_partitioning_keys share a single flat bookmark across parent contexts. • Add test verifying full-table streams emit ACTIVATE_VERSION messages with versions derived from tap initialization time. • Add test confirming incremental child streams produce partitioned STATE bookmarks including replication key metadata. • Add test asserting children with ignore_parent_replication_key force their incremental parents into full-table replication and emit a warning. meltano/sdk
