Bump DuckDB wrapper in DuckDB provider from 1.2.1 → 1.4.x for major performance & stability improvements

[ErenKrt]

Summary
The DuckDB provider currently ships with a DuckDB wrapper pinned at 1.2.1, which pulls in an older DuckDB engine. DuckDB 1.4.x brings built-in encryption support, many new features, and significant performance improvements. Upgrading the wrapper to 1.4.x would meaningfully improve the provider’s capabilities and user experience.

Current Behavior

• DuckDB wrapper version: 1.2.1
• Result: Provider uses an outdated DuckDB engine, missing recent optimizer and execution improvements, security features (encryption), and new SQL capabilities.
