feat:Adds new Param in getChatMessages for better context handling

[whysosaket]

This is a proposal to introduce a new parameter in the getChatMessages function that allows us to retrieve the latest user message, enabling more accurate memory retrieval. Currently, Mem0 Memory uses get_all to fetch all user memories, but this change would allow us to perform a semantic search, which is more efficient for handling context.

I'd like to understand if there's a better approach to achieve this, and whether it makes sense to apply the same logic to other components as well. Thanks!

Changelog

• Enhanced getChatMessages Method: Introduced a new parameter currentMessages to allow for dynamic message retrieval based on the latest user input, improving the context handling during chat sessions.
• Improved Message Handling: Updated logic to prepend messages from currentMessages to the chat history, ensuring that the latest user input is considered when fetching the memories.

Hi @chungyau97,
Could you please review this and confirm that this method works or is there a better way to handle this use-case?
