Workers AI - Z.ai GLM-5.3 now available on Workers AI

@cf/zai-org/glm-5.3 is now available on Workers AI. It is Z.ai’s flagship agentic coding model, built for long-running, tool-driven development workflows rather than single-turn chat. GLM-5.3 uses the same base model as GLM-5.2, with every gain coming from post-training.
