Constant background traffic to collab.zed.dev #27570

Description

Summary

On both Windows (dev) and macOS (production) a running instance of Zed was constantly exchanging small (like keepalive sized) packets to/from addresses that resolved to llm.zed.dev.

Steps to trigger the problem:
(I'm making assumptions as restarting Zed on both platforms the issue did not return immediately)

  1. Open Zed
  2. Do some stuff
  3. Put the machine to sleep for a while (maybe overnight?)
  4. Wake machine
  5. Observe constant round-trip traffic to llm.zed.dev

Actual Behavior:

"Lots" of traffic (not high bandwidth, but constant - was every ~0.5s on Windows, and even faster on macOS) - enough that it's keeping the wifi powered up constantly, aka draining battery.

Expected Behavior:

No need for traffic unless it's doing something useful.
