LM Studio doesn't show the context token wheel (#53790) because token usage is never reported in streaming responses. Causes: 1. `stream_options` was missing from the request. Without `stream_options: { include_usage: true }`, the LM Studio API omits `usage` from every streaming chunk entirely. 2. The event mapper discarded usage data in the final chunk. OpenAI-compatible servers send the usage summary in a trailing chunk that has an empty `choices` array. The old guard treated that as an error, so even when usage was present it was thrown away before emitting a `UsageUpdate` event. Fix: - Add `StreamOptions { include_usage: bool }` and `stream_options` to `ChatCompletionRequest`, and always set it to `true` for streaming requests. - Move usage handling in `LmStudioEventMapper::map_event` to run *before* the empty-choices guard, mirroring the OpenAI provider's approach. - Add four unit tests for `map_event` covering the fixed behavior. Release Notes: - Fixed LM Studio not showing the context window usage wheel. <img width="1184" height="1080" alt="Screenshot_20260527_130449" src="https://github.com/user-attachments/assets/97eb8500-39dd-4824-aaf8-f0422b62119d" /> --------- Co-authored-by: Gabriele Ancillai <gabriele.ancillai@sofka.com.co> Co-authored-by: Bennet Bo Fenner <bennetbo@gmx.de>
