Lower HTTPX connection pool limits from 1000 to configurable defaults (200 max connections, 100 max keepalive) to prevent flooding agent pods with concurrent requests during high load. Excess requests now queue at the pool level instead of all hitting OpenAI simultaneously.

- Add `num_retries=3` default to LLMConfig so litellm retries on OpenAI 429 rate limit errors with built-in exponential backoff - Increase Temporal DEFAULT_RETRY_POLICY from 1 attempt (no retries) to 3 attempts with exponential backoff (1s, 2s, 4s... up to 30s) This complements the HTTPX connection limit reduction in agentex backend (scaleapi/scale-agentex#144) to address OpenAI rate limiting under high concurrent load.
