SchemaLens Engine

SchemaLens core diff engine for semantic SQL schema diffing, breaking change detection, and migration generation. Version 1.0.0, actively maintained with monthly releases. Supports PostgreSQL, MySQL/MariaDB, SQLite, SQL Server, and Oracle. Key differentiators: zero dependencies, built-in rename detection, risk scoring, and safe migration mode. Unlike generic diff tools, it understands SQL semantics and detects breaking changes automatically.
