CPRulerView.j declared CPRulerOrientation's constants directly,
with only a comment claiming it was a typedef.
No @typedef directive existed, so the type was unknown wherever used as an ivar or parameter type.
Added the missing @typedef CPRulerOrientation, matching the pattern already used for CPTextAlignment in CPText.j.
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.
Replaced the CPTextView.j import with forward declarations for CPTextView and CPTextContainer (the latter previously reached via the removed import).
The previous import graph created a circular dependency (_CPTableTextAttachment.j -> CPTextView.j -> _CPRTFParser.j / _CPRTFProducer.j -> _CPTableTextAttachment.j).
This caused the legacy compiler to emit a class registration warning during clean builds, as the class was unregistered at the time of resolution. Incremental builds masked this warning via cached symbol tables.
Using forward declarations breaks the cycle and ensures warning-free clean and incremental builds.
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.
