## Description This PR ports TimechoDB MR !6798 to the latest Apache IoTDB master. ### Move OPC UA sink out of the server - Move the OPC UA sink implementation and example into the new library-pipe reactor module. - Remove OPC UA from the built-in Pipe plugin registry and DataNode dependencies. - Build an isolated fat JAR and package Pipe library artifacts in a dedicated distribution ZIP. - Register the external OPC UA plugin explicitly in integration tests. ### Preserve shared behavior - Share tablet-event transfer logic between the OPC DA sink and the external OPC UA sink. - Preserve server/client reuse while guarding reference counts against failed customization and repeated close calls. - Keep Milo dependency management local to library-pipe. ### Apache compatibility - Exclude TimechoDB-only initial-fetch and remote-sink features. - Exclude private Maven coordinates, signing configuration, and branding. - Update binary license information for the packaged Bouncy Castle dependency. ### Validation - [x] mvn test -pl library-pipe/opc-ua-sink (19 tests) - [x] mvn verify -pl library-pipe/opc-ua-sink -DskipTests - [x] mvn test -pl iotdb-core/datanode -Dtest=PipeSinkTest,PipeSinkSubtaskManagerTest (23 tests) - [x] mvn test-compile -pl integration-test -P with-integration-tests -DskipTests (858 test sources) - [x] Fat JAR contents and signature metadata inspected This PR has: - [x] been self-reviewed. - [x] added documentation for new or modified features or behaviors. - [x] added or updated license information. - [x] added unit tests or modified existing tests to cover new code paths. - [x] added integration test coverage. ##### Key changed/added classes (or packages if there are too many classes) - library-pipe/opc-ua-sink - PipeTabletEventTransferUtils - BuiltinPipePlugin - IoTDBPipeOPCUAIT - distribution/src/assembly/library-pipe.xml -- This is an automated message from the Apache Git Service.
