- Remove incorrect is_truthy() check that was blocking value replacement
- Consolidate duplicated typeof handling into evaluateTypeofForDefine helper
- Remove redundant undefined checks in typeof evaluation
- Simplify code by using recursive helper function instead of manual duplication
The typeof evaluation now uses a single helper function that handles both
identifiers and dot expressions consistently, reducing code duplication
and making the logic clearer.
