OpenAI SDK v2.31.0

v2.31.0, released 2026-04-08, adds a `phase` field to conversation messages, support for short-lived tokens, raw data over websockets, and an indices array format for query/form serialization, while also briefly adding then removing `web_search_call.results` from `ResponseIncludable`. The update matters because it expands client and API capabilities and fixes a query-parameter merging bug that could overwrite hardcoded params, with the changelog also noting docs updates for vector store file parameters and test dependency bumps to steady v0.20.2.
