- Add internal access tracking to distinguish me.field from external.field access
- Interpreter correctly allows methods to access their own private fields
- VM tracks object class context during method calls for visibility checks
- Fix VM nested box declaration collection in collect_box_declarations
- Both interpreter and VM now pass all visibility tests consistently
Test results:
- visibility_ok.nyash: ✅ Internal private access allowed in methods
- visibility_error.nyash: ✅ External private access correctly blocked
- All private fields accessible from within their own methods
- Public fields remain accessible from anywhere
