The stub helper pattern required a leading static and a plain signature,
so exports calling helpers in anonymous namespaces, or helpers with
noexcept, a trailing return type or a pointer next to the name, counted
as done. The pattern now anchors at line start, makes static optional,
skips APS5_VABI exports and control keywords, and accepts those suffixes.
