Research direction

The issue requires writing integrated and e2e tests for the TCP proxy plugin in Apache ShenYu. Start by examining existing test examples in the project, such as those in the shenyu plugin directory. The assigned developer may have started work; check comments and linked branches. Implement tests using JUnit and possibly testcontainers for integration testing. Ensure coverage of TCP proxy functionality including connection handling and data forwarding.
