- Add error-utils module with serializeError and sanitizeError utilities
- Enhance IPC error handling to capture full error context including stack traces
- Add logError helper function for consistent error logging across the application
- Update console and file log formats to properly serialize error objects
- Replace all basic error logging in BIPUsersDAO with structured logError calls
- Add ErrorLike and SerializedError type interfaces for type safety
This improves debugging capability by preserving full error details in development
while sanitizing sensitive information in production logs.
