- Introduced `xaiNormalizeReasoningSummaryData` and related functions to normalize `reasoning_text` events into `reasoning_summary` shapes for standardization.
- Updated WebSocket and streaming logic to process normalized reasoning summary events correctly.
- Enhanced tests to validate normalization, order of events, and output structure in both stream and non-stream scenarios.
- Added methods for managing and tracking WebSocket transcript state, including recording, prepending, and replacing transcript inputs.
- Implemented `executeCompactionTriggerFromWebsocketContext` to support compaction triggers using recorded transcript context.
- Enhanced upstream-downstream ID mapping with additional utilities and state synchronization.
- Expanded test coverage to validate transcript state management, compaction payload generation, and WebSocket response handling.
- Developed `XAIWebsocketsExecutor` for handling xAI Responses via WebSocket transport.
- Introduced session and state management with `codexWebsocketSessionStore` and `xaiWebsocketIDStateStore`.
- Added robust ID mapping for upstream and downstream request/response sequences.
- Enhanced error propagation and handling of WebSocket terminal events.
- Included utility methods for WebSocket request preparation, connection management, and state tracking.
- Added foundational support for compact and streamed responses via enhanced session tracking.
