JDK-agnostic aggregator for the UnsafeOperations SPI: bundles every version-specific implementation and selects the right one at runtime. Depend on this single artifact instead of a specific unsafe-operations-impl-* module. Compiled to the lowest supported class-file version (Java 11) so its provider classes load on every supported JDK; the version-specific implementations are pulled in at runtime and loaded reflectively only when they match the running JDK.
