fix: flush all native providers on shutdown to prevent data loss
Shutdown/close/flush now properly flushes all 4 components in parallel: metadataIndex, graphIndex, HNSW dirty nodes, and storage counts. Previously only counts were flushed, causing native provider data loss on restart. Also: - Wire roaring, msgpack, entityIdMapper provider consumption from plugins - Fix allOf filter O(n²) intersection → O(n) Set-based - Fix ne/exists negation filter to use Set-based exclusion - Add setMsgpackImplementation() swap in SSTable for native msgpack - Add setRoaringImplementation() swap for native CRoaring bitmaps - Add getAllIntIds() to EntityIdMapper for bitmap operations - Remove TypeAwareHNSWIndex from default index creation path - Export memory detection utilities from internals - Clean up 26 permanently-skipped dead tests
