🤖 Prompt for AI Agents 
In src/main/java/com/example/solidconnection/chat/domain/ChatMessage.java at
lines 28-29, the content field lacks validation to prevent empty or
whitespace-only messages. Add validation logic, such as using annotations like
@NotBlank or implementing a custom validator, to ensure the content is neither
null, empty, nor only whitespace before persisting or processing the message.
