Pull Request Overview
This PR refactors type inference logic by moving several type inference methods from the general inference module to the more precise "certain type inference" module. This change improves the accuracy of type inference by handling cases where the type can be determined with certainty.
- Move reference, tuple, async block, array, and cast type inference from general to certain type inference
- Remove duplicate inference rules that were already present in both modules
- Update expected test results to reflect improved precision
