feat(eve): Frontend integrations should supports auto start streaming and auto-fetch offline outputs.

[lchrennew]

What problem are you trying to solve?

I'm writing chat boxes in Vue.js using eve/vue. I store the session and events in localStorage.

After sent a message to an agent, when I close the window / refresh the page before streaming complete, the session truncated at where it goes on page reload.

Proposed solution

What is expected:

• Load offline outputs generated between page unload and reloaded
• Auto start streaming the going on events.
