Closes #52 E2E tests were failing in CI because they relied on real API endpoints that returned 404 errors. This adds a local mock OpenAI-compatible server that handles all test scenarios without external API dependencies. Changes: - Add mock-openai-server.ts in packages/ai/__tests__/helpers/ - Add mock-openai-server.ts in packages/agent/__tests__/helpers/ - Update openai-compat.e2e.test.ts to support MOCK=true mode - Update tool-calling.e2e.test.ts to support MOCK=true mode - Update react-loop.e2e.test.ts to support MOCK=true mode - Update e2e.yml workflow to set MOCK=true The mock server handles: - Non-streaming and streaming chat completions - Tool calls (single and multiple) - Tool result summaries (ReAct loop support) - JSON/structured output responses Usage: MOCK=true pnpm test (runs E2E tests against mock server) All 7 E2E tests pass with MOCK=true, no external API needed.
