fix(langchain): type checkpointer thread config for mypy The regression test's `thread` config dict lacked a `RunnableConfig` annotation, which mypy's `agent.invoke` overload resolution needs to pick the right signature. CI's `lint_tests` job caught this. Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>

fix(langchain): clear stale `structured_response` between checkpointed turns Closes #36957 `_build_commands` only wrote `structured_response` into state when the model call produced one, so a checkpointer-persisted value from a prior turn stuck around. The routing edges only checked `"structured_response" in state` (key presence), so a turn whose first attempt failed validation and needed a retry would exit early with the previous turn's stale value instead of continuing the retry loop. Now `_build_commands` explicitly clears `structured_response` to `None` when the agent has a `response_format` configured but this call didn't produce one, and the routing edges check `state.get("structured_response") is not None` for freshness instead of key presence.
