📝 Walkthrough

Walkthrough

PostgreSQL relationship and attribute inserts now group up to 500 records per SQL statement. The changes preserve conflict handling, ellipsis normalization, protobuf JSON serialization, and error propagation.

Changes

PostgreSQL insert batching

Layer / File(s)	Summary
Batch relationship inserts internal/storage/postgres/data_writer.go	Relationship records are grouped into batches of 500. Each batch uses a query-builder multi-row insert with conflict-ignore handling.
Batch attribute inserts internal/storage/postgres/data_writer.go	Attribute records are grouped into batches of 500. Values remain serialized with protojson, and generated statements are queued.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 0af7a

The PR updates PostgreSQL batch insertion to skip empty collections and group writes while preserving existing conflict and serialization handling; no actionable merge-blocking risk remains beyond normal checks and review.
