Changelog

v0.2.0

• Automatic literal type coercion in comparisons. When a literal is compared against a typed field (e.g., performed_on >= "2026-05-20" where performed_on is a :date), the literal is now wrapped with type/2 so Ecto and the database driver cast it to the column's type. Previously this could fail in PostgreSQL with errors like operator does not exist: date >= text.
• Coercion sources its type information from the schema (__schema__(:type, _)), from the keyword form of :allowed_fields, and by walking association paths to the leaf field. Works for ==, !=, >=, <=, and includes in both operand orders.
• Coercion is skipped when the literal's natural type already matches the field (e.g., string-vs-string, integer-vs-integer), so existing queries are not affected.
