Ethan 21d08241e9 fix(coderd/x/chatd): recover timed out agents (#27254) ...

Closes CODAGT-802

Coder Agents only escalated failed workspace dials when the agent had
connected and later disconnected. An agent that never connected and had
already exceeded its `connection_timeout` stayed on the soft retry error
indefinitely, so a chat could keep attempting tools against an unhealthy
workspace.

To fix, we'll classify the latest agent after a failed dial and return
stop/start recovery guidance when its status is `timeout`. Agents still
connecting, including templates with `connection_timeout = 0`, keep the
existing retryable behaviour.
