feat(ai): Add zAI provider support

- Add 'zai' as a KnownProvider type - Add ZAI_API_KEY environment variable mapping - Generate 4 zAI models (glm-4.5-air, glm-4.5v, etc.) using anthropic-messages API - Add comprehensive test coverage for zAI provider in generate.test.ts and empty.test.ts - Models support reasoning/thinking capabilities and tool calling
