[RFC] Enhance Build Process Feedback with Loading Animation

[actopas]

How do you envision this feature/change to look/work like?

During the development of my plugin card, for some reason, the build process once exceeded 40,000ms. When saving the code, there is no specific perception of whether everything is in the queue, or the prompt is being built. The most annoying thing is that after multiple hot reloads, I look at the terminal page 🟢 DONE | Extension re-packaged in, and it is difficult to tell whether the build is now completed. So I hope to add a loading information prompt at the beginning of the build/hot reload, and no longer display loading when the loading is completed or failed, to improve the perception of the build and hot reload.

What is the purpose of this change/feature? Why?

• Provide a better user experience by letting users know that a build is in progress;

• clearly indicate the start and end of a build;

• and stop the loading animation in time when a build fails to avoid user confusion;

(OPTIONAL) Example implementations

Specifically, the functional implementation:
Display the loading animation when the build/hot reload starts in the terminal
Stop and remove the animation when the build succeeds or fails
Use the startLoading() and stopLoading() functions to control the loading animation
