The hnsw_rs crate, version 0.3.4, is vendored in source form at vendor/hnsw_rs
and carries five ZeusDB patches, one to the reverse link layer assignment, one
seeding level assignment so index builds are reproducible, one guarding the
neighbour list overflow pop against stranding a point's last inbound link, one
correcting the filtered search path so it cannot panic or return an empty
result set, and one correcting the per-layer capacity reservation so a declared
index size does not commit hundreds of times the memory it needs. See
vendor/hnsw_rs/ZEUSDB-PATCH.md for the patch record. hnsw_rs is dual licensed
