Pull Request Overview
Adds helper shortcuts and corresponding CodeQL implementations to simplify accessing function parameters and call arguments in the Rust AST.
- Introduces synthetic
paramsandargsfields in the schema forCallableandCallExprBase, respectively. - Implements
getParamandgetArgoverrides in the CodeQL internal modules. - Updates imports, linguist settings, and generated file lists to wire in new extractor tests.
