DCA looks good.

Pull request overview

This PR updates the Ruby CodeQL libraries to improve evaluation behavior (per the referenced DCA check), primarily by adding/adjusting QL pragmas and introducing small wrapper predicates to encourage more predictable/efficient binding and inlining.

Changes:

• Added/expanded uses of pragma[only_bind_into], pragma[inline], and pragma[inline_late] in several core/framework libraries.
• Refactored a few predicates/methods into *Impl implementations with thin inline wrappers (notably in AST scope handling and dataflow node scoping).
• Minor internal factoring in ActiveRecord and dataflow dispatch to isolate sub-conditions into dedicated predicates.
