[bot] Instrument runwayml (62,131 weekly downloads) #853

What's missing

runwayml (the official Python SDK for Runway's generative video/image API) has no native instrumentation in the Braintrust Python SDK. There is no py/src/braintrust/integrations/runwayml/ directory, no entry in py/pyproject.toml [tool.braintrust.matrix], and no nox session in py/noxfile.py. The SDK exposes execution-oriented generation calls (confirmed in the official README: client.image_to_video.create()) that submit and poll asynchronous generative video jobs — the same class of "call out to a generative model and capture the execution" behavior Braintrust already instruments for other media/generation providers.
