Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: Span count assertion inconsistently weakened in one test
  • I strengthened test_streaming_create_message to assert exactly one gen_ai.chat span instead of selecting the first match, restoring strictness without failing on unrelated subprocess spans.
