[Bug] Stream stalls immediately on first API request with "Waiting for API response" retry loop

Bug Description
I am encountering a persistent and recurring issue where Claude Code immediately runs into a stream stall and gets stuck on "Waiting for API response · will retry in..." right after starting a fresh session. This issue is NOT an isolated event; it has been happening consistently for the past several days. Since it occurs on a brand new launch, it completely rules out any context window accumulation or token size pressure. The streaming connection simply fails to sustain right from the first request, leading to mid-stream stall errors. ### Steps to Reproduce 1. Start a fresh Claude Code session in a clean workspace. 2. Submit the initial prompt or wait for the tool initialization. 3. The stream immediately stalls, displaying the "Waiting for API response" countdown loop, and eventually fails entirely.
