Relationship and attribute batch inserts now group up to 500 records per SQL INSERT statement. Empty inputs return immediately. Existing encoding, normalization, conflict handling, and error propagation remain in place.

Changes

PostgreSQL Batch Inserts

Layer / File(s)	Summary
Chunked relationship and attribute inserts internal/storage/postgres/data_writer.go	Relationship and attribute records now use Squirrel-built multi-row inserts with a 500-record chunk size. Attribute values remain protobuf-JSON encoded. Existing relationship normalization, conflict handling, and SQL errors remain preserved. Empty inputs return without queuing statements.

Estimated code review effort: 3 (Moderate) | ~20 minutes
