How the top-level servers array is combined across inputs.
'first' — the first input that declares servers wins and the rest are
discarded. This is the historical behaviour and remains the default: the
tool is aimed at putting several services behind one API gateway, where the
gateway's servers are canonical and a backend's own URLs are an
implementation detail that must not leak into the published document.
'concat' — every input's servers, in input order, deduplicated by URL.
For people merging microservice specs to document all of them at once.
