Sentiment clicks create gh events request

Whether used for human comments, copilot comments or comments - its useful to be able to understand how developers are interacting with them (thumbs up, thumbs down, emojis, etc).

Today, the documented solution is to interrogate the gh api to pull the comments and parse them. The issue is that its very easy to get the api comments throttled, and it ends up being a lot of work to just get something that should otherwise just emit a signal that one can subscribe to.

thank you for the consideration.

审查 Ruby webhook server framework 及其现有事件模型，然后确定如何将 GitHub 评论情感操作表示为可订阅事件。完成标准是：framework 为人工评论和 Copilot 评论中的点赞、点踩和 emoji 交互提供清晰的事件信号，并记录预期的 payload 和订阅行为。
