SharpCoreDB.VectorSearch v2.1.0-RC.3

SIMD-Accelerated Vector Similarity Search

Semantic search and similarity matching 50-100x faster than SQLite using HNSW indexing and SIMD acceleration.

Patch updates in v1.9.5 (archived; current release v2.1.0-RC.3)

✅ Parameterized query binding fixed (Issue #336): named-parameter binding is token-aware, so parameter names that are prefixes of others (e.g. @t vs @tid) no longer corrupt the SQL.
✅ Server parameter pass-through fixed (Issue #337): request.Parameters are forwarded on gRPC, the binary (PostgreSQL) protocol and WebSocket.
✅ ULID encoding is now standards-compliant: ULIDs follow the official Crockford Base32 spec and are interchangeable with Python/Java/Go implementations.
✅ NuGet dependencies updated to their latest stable versions.
✅ Aligned package metadata and version references to the synchronized 1.9.5 release line.
✅ Release automation now publishes all packable SharpCoreDB packages in CI/CD.

Features

✅ Inherits metadata improvements from SharpCoreDB v1.9.5
✅ Phase 8 complete: HNSW-accelerated semantic search
✅ 50-100x faster than SQLite
✅ NativeAOT compatible
✅ Zero breaking changes

🚀 Key Features

HNSW Indexing: Hierarchical Navigable Small World graphs
SIMD Acceleration: Vectorized distance calculations
