perf: export modules in core

[wibus-wee]

What's Changed

I export the runtime from core to reduce the number of dependencies that need to be installed on the client side

And i change the package name of core: @jwcjs/core --> jwc --> jwcjs

Before

import { JwcComponent, Component } from "@jwcjs/core";
import { h } from "@jwcjs/runtime";

Now

import { JwcComponent, Component, h } from "jwcjs";

jwc has been existing package takes up: https://www.npmjs.com/package/jwc
