CPRulerView.j referenced CPTextTab (isKindOfClass: and alloc/init) without a declaration.
Added @class CPTextTab; to resolve the symbol reference. A forward declaration was utilized rather than importing CPParagraphStyle.j to minimize dependency coupling, despite the absence of a circular import risk.
Resolves build warning.
CPRulerView.j did not import CPScrollView.
A direct import would create a cycle, since CPScrollView.j already imports CPRulerView.j.
Added a forward declaration instead.
