  • Switches unit test template proto imports from method.ref_types (recursive) to method.flat_ref_types (direct method parameters only).
  • Prevents unused transitive _pb2 imports from being emitted into unit test files.
  • Deletes legacy synthtool post-processing script .librarian/generator-input/client-post-processing/remove-unused-imports.yaml.

Fixes: #16359

Code Review

This pull request deletes an unused import patch configuration file and updates the Jinja templates for test generation (test_%service.py.j2) in both standard and ads-templates to use method.flat_ref_types instead of method.ref_types. I have no feedback to provide.
