fix: add detailed error capture for Windows cjbind test

Enhance Windows test step to capture and display DLL-related errors
that might be silently failing. This includes:
- File existence verification
- Explicit error output capture (stderr)
- Exception handling with detailed error messages
- Optional dumpbin dependency check
