/**
 * Spark 4.0-compatible override of the `paimon-spark4-common` `Spark4ArrayData`. Spark 4.1 added
 * `getGeography` / `getGeometry` abstract methods (returning the 4.1-only `GeographyVal` /
 * `GeometryVal` types) onto `SpecializedGetters`, which the 4.1 version of this class overrides.
 * Those methods (and their return types) do not exist in Spark 4.0.2, so we publish a slim variant
 * without them. The maven-shade-plugin pulls both jars into the final paimon-spark-4.0 bundle and
 * the local `target/classes` copy takes precedence at runtime, satisfying the Spark 4.0 class
 * loader which would otherwise refuse to load the 4.1 bytecode with the missing `GeographyVal` /
 * `GeometryVal` references.
