The fixtures embedded PHP namespace paths (\App\Bar, App\Command) as plain strings, so
\A / \C were invalid escape sequences (SyntaxWarning now, SyntaxError in a future Python).
Double the namespace backslashes; the \n newlines are unchanged.
A PHP `new Foo()` emitted no edge. Add object_creation_expression to the PHP call types and
emit a calls edge to the constructed class (namespaced names resolve to the last segment),
consistent with the C# (#2998) and TypeScript (#3135) object-creation handling. Dynamic
(new $var()), self/static/parent, and unknown external constructions fabricate nothing.
