LifeCycles

Currently, we are working on Props in parallel with #25,
but it seems that we can proceed with LifeCycles on a separate axis, so we will continue with it during the discussion as well.

Some implementations seem to be able to start, while others cannot be started yet or require discussion.

NOTE:
It seems there are a few people trying to implement the onUpdated hook,
but it might be better to discuss it here first. Starting from the design.

We need to wait PR #82 to refactor reactivity system.

i think we can use MutationObserver watch instance state(attr/characterData/subtree/children).When changes occur, trigger the update hook

detail: #87

I integrated the Render Watch API in #86. To implement the Updated And BeforeUpdate Hooks, I will emit update events within this Render Watch API.
