What's New

Fixes critical graph query counting bug and index population performance issues

New Features

Reference-map builder now preserves multiplicity for star aggregations.
Index population now merges main matrix and delta-plus for safe batch resume.

Improvements

Reduced write stall time from ~1.5s to ~5ms for edge batch population.
Added plan-cache safety for the new star aggregation reference logic.

Bug Fixes

Fixed `count(*)` under-counting parallel edges in graph queries.
Resolved index population skipping rows or hanging on unsynced delta matrices.

Upgrade Notes

Queries using `count(*)` on parallel edges will now return correct counts. Index population performance should improve significantly with reduced write stall times. No configuration changes are required.
