1921118 - Send a connection packet from the frontend to communicate information about the frontend

Status: RESOLVED FIXED

(DevTools :: Framework, enhancement)

Description

[Alexandre Poirot [:ochameau]]

For now, only the server emits a packet on connection with info about the server, like applicationTraits.
But the frontend doesn't emit anything to the server about itself.

Servo is using the DevTools frontend and would like to support many frontend versions by delivering different actors.
But for that, it should receive some info about the frontend version.

The suggested connect method call on the Root actor would emit a packet like this:

{
  "type": "connect",
  "firefoxVersion": "132.0a1",
  "to": "root"
}

Coming here from Servo. This would be so helpful, thanks!

I made a small change to the final packet and should look like this:

{
  "type": "connect",
  "frontendVersion": "133.0a1",
  "to": "root"
}
