Subject: [PATCH] fix(memory-vector): seed JVector index from SQLite on
 VectorMemorySystem.open()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

После рестарта in-RAM граф JVector создавался пустым (seedEntries не
проходились из metaStore), поэтому search возвращал [], пока не
появлялись новые upsert'ы — память терялась после каждого рестарта.

- VectorMemorySystem.open(): JVectorMemoryIndex(dimension, metaStore.allEntries())
- SqliteMemoryMetaStore.open(): убрал случайное двойное конструирование
- регресс-тест openSeedsIndexFromSqliteAfterRestart (save → close → open → search)
