improve: duplicate git exec in hmr of git changelog plugin

[northword]

HMR 中重复的 Git 请求。

当前在 changelog.vue 中和 contributors.vue 中分别 send 了一次，这导致 Git 实际上被运行了两次（即使有设置的缓存，但是似乎因为两次执行的太近了，导致两次都是实际运行了 Git 的，从下面这个日志可以看出：

不知道配合 VueUse 的 useMounted + watch 能不能做一个更好的 store 共享一下。

刚刚试了试在 client throttle ，似乎不可行。

也许可以在 vite 端做 throttle ；

或者做一个更大的组件，把 Changelog 和 Contributor 都放进来，这样就只需要在这个更大的组件里 import.meta.hot.send ，这样就可以避免两个组件都发送。

useMounted + watch 这种我不太清楚怎么实现。

(I'm not sure I'm understanding this correctly)

In addition to Git running twice, Vue component reloads were performed 4 times:

Changelog.vue and contributors.vue each resulted in 1 Git run

Each Git run resulted in the following two events:

• nolebase-git-changelog:updated
• virtual:nolebase-git-changelog

We might need to wrap these two components into one big component and control whether or not to show separate ones via props/options. Importing on demand might be possible with asynchronous components?

Then on the hmr related logic part, maybe

• On the vite side, just send data, don't touch the value of the virtual module, and let the client side receive the sent data and re-assign the value.
• No more sending data on the vite side, accept(virtual:nolebase-git-changelog) on the client side seems to be sufficient.
