fix: handle missing fields in OpenAI ResponseErrorEvent stream events - #34

Conversation
…formant providers The Codex backend sends SSE error events without `code`, `param`, or `sequence_number` keys. The @effect/ai-openai schema required these fields, and the UnknownResponseStreamEvent catch-all rejected known types like "error", so the stream decoder crashed instead of surfacing the error. Also upgrades @effect/* from rc.109 to rc.112, which subsumes the prior patch (reasoning "max", XaiErrorBody, 402 handling, billing_insufficient_balance).
