## Changes

### PR [#2255](https://github.com/danielmiessler/Fabric/pull/2255) by [ksylvan](https://github.com/ksylvan): fix: SSE streaming fixes (supersedes #2102, #2128, #2213, #2242, #2247)

- Fixed SSE streaming behavior by correcting chat SSE headers and suppressing completion events after errors.
- Prevented canceled chat requests from blocking stream update delivery.
- Upgraded the OpenAI SDK to v3.71.1 and refreshed dependency manifests.
- Restored Azure deployment routing through native SDK endpoint configuration. Chat Completions use deployment-scoped paths; Responses use `/openai/responses` with the deployment name in the `model` field. Azure endpoints must use HTTPS, and credentials do not follow cross-origin redirects.
- Improved error handling by preserving provider error details, surfacing Claude scanner failures, and keeping streaming Ollama error responses labeled with NDJSON headers.
