Experimental DuckDB support for Oban through the QuackDB Ecto adapter.
The integration provides Oban.Engines.QuackDB for job orchestration and
Oban.Migrations.QuackDB for durable job storage.
QuackDB and DuckDB's Quack protocol are experimental. The initial integration is intentionally limited to single-node operation without prefixes or the PostgreSQL-specific Reindexer plugin.
