"""Best-effort early import of the OpenAI SDK's native streaming parser: on some
Windows installs ``jiter``'s native extension imports fine from the venv but fails
when first imported inside the threaded streaming path. Loading it once at
agent-package import avoids that while keeping the SDK's normal error path for
genuinely broken installs."""
