fix: Implement N-depth charm reference detection with robust error handling

- Added recursive traversal of sourceCell chains to find resultRefs
- Implemented safe traversal to avoid triggering Copy trap errors
- Fixed cycle detection by tracking object references directly
- Added improved error handling to gracefully handle issues without crashing
- Added safeguards to prevent array access issues and property access errors
- Limited the maximum number of references to avoid UI overload
- Thoroughly tested with nested reference chains

Fixes #758
