Investigate the intermittent (~20-30%) long-turn failure "Lost connection to the AI provider" = AI_RetryError / read ECONNRESET on the gitmost->z.ai link (browser-agnostic, mid-turn). Pure instrumentation, no behavior change: - ai-http-diagnostics.ts: a passive fetch wrapper injected into the OpenAI-compatible (z.ai) client. Per provider HTTP call it logs time-to-headers/status on success, and on a pre-response rejection the latency, error code/cause, request-body size and idle-gap since the previous call. The Response is returned untouched (streaming intact), errors rethrown unchanged; no retry/timeout/dispatcher. - ai.service.ts: wire the instrumented fetch into the openai case only. Lets us classify the reset as connection-phase vs mid-stream before choosing a fix, without repeating the reverted RetryAgent (#140). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
