11.0.286

Summary

DuckDB engine upgrade release.

Changes

• Bump embedded DuckDB from 1.5.3 to 1.5.4 (duckdb-go/v2 v2.10504.0) (#852).
• Bundled extensions (ducklake, sqlite_scanner) synced to v1.5.4.

Upgrade notes

• Reinstall from release packages or rebuild from this tag so embedded DuckDB and bundled extensions stay on the same version.
• Verify after upgrade: homer-core system --duckdb-version should report 1.5.4.
