fix(metadata): excludeVFS filter consistency + VFS-aware statistics API
Bug Fixes:
- Fix getIdsForFilter() anyOf early return - now intersects with outer-level
fields like vfsType, ensuring excludeVFS works with multi-type queries
- Fix update() noun removal - includes type in removal metadata so noun
index is properly updated when entities change types
New Feature:
- VFS-aware statistics API using existing Roaring bitmap infrastructure
- brain.counts.byType({ excludeVFS: true }) - hardware-accelerated SIMD
- brain.counts.getStats({ excludeVFS: true }) - O(1) bitmap cardinality
- Uses existing isVFSEntity field index (no new data structures)
Performance:
- O(log n) bitmap load + O(1) intersection (AVX2/SSE4.2 accelerated)
- Zero new storage overhead - reuses existing indexed fields
- Scales to billions of entities
