fix(closure): handle static variables in closure use references

- Added check for staticVars when processing closure use references
- Prevented redeclaration of static variables as local variables in closures
- Updated variable resolution logic to include static variable scope
- Added comprehensive test case for static variable closure reference behavior
- Fixed variable name collision in preprocessor class constant handling
- Updated version number to 0.4.1
