Pull request overview
This PR makes small internal refactors in the core implementation code, primarily tightening constructors on an internal utility and modernizing list access using Java 21 APIs (aligning with the “enterprise counterpart” requirement mentioned in the PR description).
Changes:
- Narrowed
DynamicIntArray’s no-arg constructor visibility and removed a redundant constructor overload. - Replaced
list.get(0)withlist.getFirst()inDefaultVariableReferenceGraphfor clearer intent on sequenced lists.
