Refactor/kol get mentions

[Xm0onh]

This PR is about moving thread of conversation from responseGenerationNode to mentionNode. Now, the thread is also being used in engagementNode, toneAnalysisNode and "responseGenerationNode. The algorithm of fetching mentioned modified and improved by n` factor.

• The changes in this PR will effect memory viewer. I'll open a seperate PR for that.
• It would be great to craft the prompts further to take the thread into account properly.
• One of the nice thing to have is to summarize a conversation thread and extract the important parts and use them instead of passin the whole thread as a prompt. This change will make agent more efficient when we are dealing with large threads.

@jfrank-summit I discovered a bug in my getThread implementation. For now, let’s keep the new version as a placeholder. I’ve also added the previous function as the origin function for fetching a conv thread.

Let’s prioritize merging this PR since retrieving the thread has been moved to the start of the workflow. I have a more urgent task to address and will revisit this optimization later.
