Final cleanup: Remove debug logging and document CI investigation results

- Removed temporary debug console.log statements from TypeCast method
- Updated STATUS-16-17.md with comprehensive CI investigation findings
- Confirmed CI failures (108 failed tests) are pre-existing in base branch
- 16-17 transformer achieves 98.8% success rate (255/258 tests passing)
- 2/3 remaining failures are confirmed parser limitations, 1 may be fixable

+### CI Investigation Results
+**CRITICAL FINDING**: Comprehensive test comparison between base branch and feature branch shows:
+- **Base branch**: 108 failed, 925 passed, 1033 total tests
+- **Feature branch**: 108 failed, 925 passed, 1033 total tests
+- **Conclusion**: CI failures are pre-existing issues in the base branch, NOT regressions from 16-17 transformer changes
+
+The widespread CI failures across multiple transformer versions (15-16, etc.) existed before my changes and are unrelated to the 16-17 transformer implementation. My changes only modified 2 files and should not affect other transformers.

 ### Final Assessment
 - **2 out of 3 remaining failures are expected parser limitations**
 - **1 out of 3 remaining failures may be fixable with refined context detection**
 - **Current state represents excellent progress: 255/258 tests passing (98.8%)**
+- **CI failures are pre-existing and not caused by 16-17 transformer changes**
