v1.11.0

✨ New Features

Context Variable Propagation in Sync Streaming

The sync streaming_generator now propagates contextvars into the pipeline execution thread. This means caller-set context, such as tracing/span IDs, request-scoped state, or authentication tokens is correctly available inside the pipeline thread during streaming execution.

The async streaming paths (asyncio.create_task, asyncio.to_thread) already handled this automatically and are unaffected.

🎨 Other Changes

• Use deepset/haystack:stable as the base Docker image instead of the previous default
