… Java generator Enables the Go-native postprocessor pipeline in the Java generator when the legacy owlbot.py script is absent. Relocates generated files directly to destination paths, bypasses staging, and refactors tests into separate Go-native API and library-level unit tests. For googleapis#6516

Code Review
This pull request introduces a native Go postprocessing flow as an alternative to the legacy owlbot.py postprocessor. It updates postProcessLibrary and postProcessAPI to check for the presence of owlbot.py and conditionally route execution to either the legacy flow or the new Go-native flow. Additionally, unit tests are added to verify both the API and library-level Go-native postprocessing paths. The reviewer feedback recommends improving the robustness of the file existence checks by explicitly handling unexpected errors from os.Stat (such as permission issues) rather than assuming any error indicates the file is missing.
…I tests and harden owlbot.py checks
