- sends UDS events to ztunnel via a socket whenever a pod is enabled for ambient mesh (whether from CNI plugin or node watcher), instructing ztunnel to create the "tube" socket.

The ambient CNI agent is the only place where ambient network config and pod redirection machinery happens.

### Outbound

Requests leaving a pod go through the "outbound" code path on port 15001.
This is where most of Ztunnel's logic lives.

For outbound traffic, we need to first determine where the traffic is destined to.
As Ztunnel operates at L4, we only have the destination IP/port (recovered via `SO_ORIGINAL_DST`).
