* fix: defensive copy in get_reviewer_agent and get_chat_agent [closes #1584] Factory functions were mutating the caller's RunnableConfig in-place via config['recursion_limit'] = DEFAULT_RECURSION_LIMIT. Add copy.deepcopy(config) at the top of each factory and switch the recursion_limit write to setdefault so a caller-supplied ceiling is respected. * fix: preserve runtime config object identities Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> --------- Co-authored-by: Fleet Agent <fleet-agent@langchain.dev> Co-authored-by: Johannes du Plessis <51395795+johannes117@users.noreply.github.com> Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> (cherry picked from commit c34e04f44da7ec7638cdafc71e0bb40e77070efd) Co-authored-by: Jacob Albert <122248719+jacobalbert3@users.noreply.github.com>
