## What changed
- Add a multi-turn scenario covering `request_user_input_async`, continued work while awaiting an answer, and delivery of the answer into the active turn.
- Add a scenario covering plugin configuration reload in an existing thread, including discovery and use of newly installed skills and MCP tools across turns.
- Render explicit tool output names and namespaces in context snapshots, with a regression test ensuring outputs do not inherit metadata from their calls.
