* 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
