v0.4.1

Added

• Added direct SQL and Ecto LIST helpers for list_contains, list_has_any, list_has_all, and unnest.
• Added Ecto SQL generation support for nested map/tuple select expressions and IN (subquery(...)) predicates.

Fixed

• Fixed Ecto nil insert values so nil is sent as a parameterized NULL instead of emitting DEFAULT.
• Fixed Ecto tagged source-field parameters in query predicates.
• Fixed Ecto lateral joins with parent_as/1 by threading explicit source context through query rendering.
• Fixed DBConnection query caching and telemetry to preserve the original parameterized SQL while sending formatted SQL to DuckDB.
• Fixed Ecto map loading/dumping for JSON-backed map fields.
