Add support for Scoping Events

Currently only normal emits are displayed, emits such as emitUp, emitTo and emitSelf are not recorded and displayed.

But we also need this ;)

[place where it is?](https://github.com/beyondcode/livewire-devtools/blob/709cf631968da4ccfb5c9059f38cae1ccc947326/src/backend/events.js#L39)

從 src/backend/events.js 的第 39 行附近開始，這裡會記錄一般 emits 以供顯示，並追蹤事件資料如何到達 DevTools UI。擴充現有的事件處理以涵蓋 emitUp、emitTo 和 emitSelf，然後確認每個具作用域的事件都已被記錄並顯示。

由索引模型根據 Issue 內容生成。
