Subject: Implement proper exception hierarchy and consistent error handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Create base exception classes:
  - VSSimulatorException: Base checked exception for all simulator errors
  - VSSimulatorRuntimeException: Base unchecked exception for unrecoverable errors
- Refactor existing exceptions to extend from base class:
  - VSEventNotCopyableException: Now includes better error messages
  - VSParseIntegerVectorException: Added constructors with cause support
  - VSNegativeNumberException: Added field name and value parameters
- Add new specific exception types:
  - VSConfigurationException: For configuration errors
  - VSSerializationException: For save/load operations
  - VSProcessException: For process-related errors
  - VSProtocolException: For protocol execution errors
- Create VSErrorHandler utility class:
  - Centralized error logging and user notification
  - Consistent error handling patterns
  - Helper methods for warning and error dialogs
- Update exception handling in code:
  - VSClassLoader: Better error messages and specific exception handling
  - Timestamp events: Catch RuntimeException for custom actions
- All 132 unit tests pass
