amoussa1229 3a92a42f57 feat: port model-fallback resilience from upstream (#1694, #1695) ... - Add httpx.TransportError to the transient-exception set so incomplete chunked reads on streamed responses trigger a fallback instead of cancelling the run (#1694 / c9f6dd86). - Rewrite fallback to alternate primary/fallback with exponential backoff instead of a single failover, so the agent survives multi-minute gateway outages spanning both providers (#1695 / c9a9a7cd). - Default backoff schedule (0, 5, 15, 30, 45) reaches past the gateway's ~30s recovery window; jittered ±25%. - On exhaustion, surface a terminal AIMessage explaining the outage instead of crashing — progress is checkpointed so the user can retrigger to continue. - Preserve fork conventions: Bedrock ClientError retryability check, sync wrap_model_call (using time.sleep instead of asyncio.sleep), and existing access-error surfacing for Anthropic, OpenAI, and Bedrock (botocore) provider errors. - Update triage ledger (c9f6dd86, c9a9a7cd → landed) and re-render triage.md.
