Subject: [PATCH] release(prebuilt): 1.1.1 (#9316)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bumps langgraph-prebuilt from 1.1.0 to 1.1.1.

Includes:

- Stop `ToolNode` from swallowing a resume value that fails an
interrupt's `response_schema` (#9232). This needs langgraph 1.2.15 or
later, which marks those errors; with an older langgraph, `ToolNode`
keeps today's behavior.
- Keep tool results out of v3 messages (#7838)

Managed Deep Agents (langchain-ai/managed-deepagents-sdk#710) will raise
its `langgraph-prebuilt` minimum to this release, so an invalid answer
to an interrupt raised inside a tool, such as a subagent, fails the
resume instead of reaching the model.

After merge, run the Release workflow with
`working-directory=libs/prebuilt`.
