More nuanced AI replies for community engagement

We've refined the instructions for our AI when it drafts replies to community posts. The goal is to make these replies sound more like a genuine community member and less like a salesperson. This means the AI will now focus on being helpful and technical, mentioning your brand more subtly, and avoiding direct website links or overly promotional language. We've also added a guideline to make replies more concise and to-the-point, skipping conversational fluff.
