This causes stalled sockets that hang until the gateway-level 120s timeout. Fix: Add isOllamaProvider() to detect localhost:11434 endpoints, and embedWithNativeFetch() using Node.js 18+ native fetch instead of the OpenAI SDK. Native fetch properly closes TCP connections on abort. Added Test 8 (testOllamaAbortWithNativeFetch) to cjk-recursion-regression test suite. Also added standalone test (pr354-standalone.mjs) and 30-iteration stress test (pr354-30iter.mjs).
