getDisplayName method

Returns the display name of this application context.

The display name is typically more descriptive than the application name and may include additional context information like:

• Context type and role
• Module or component information
• Environment-specific identifiers
• Instance sequence numbers

Example Display Names:

• "Main Application Context (Production)"
• "Web MVC Dispatcher Servlet Context"
• "Test Context #1 for UserServiceTests"
• "Batch Processing Context - JobLauncher"

Usage:

print('Operating context: ${context.getDisplayName()}');
// Output: "Operating context: AnnotationConfigApplicationContext - MyApp"
