Subject: [PATCH] fix: lower websocket session ended log severity from Error to
 Warn in Client.Run
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Description

In `pkg/ws/client.go` within the `Client.Run` reconnection loop, session termination errors returned by `c.connectAndServe(ctx)` are logged at `Error` severity (`c.logger.Error("websocket session ended", "err", err)`). During transient disconnects or routine connection renegotiation with the relay, the client automatically recovers via exponential backoff reconnects. However, logging at `Error` severity increments `container_log_messages_total{level="error"}` and triggers benign `ForagerServiceLogErrors` Prometheus alerts.

This change demotes the log severity from `Error` to `Warn` (`c.logger.Warn("websocket session ended", "err", err)`), avoiding triggering benign alerts while preserving visibility into session terminations.

- `pkg/ws/client.go`:120-123 — Logs websocket session termination at Error level during Client.Run reconnect loop

```
err := c.connectAndServe(ctx)
		if err != nil {
			c.logger.Error("websocket session ended", "err", err)
		}
```

If part of the requested change is already present in the code above, do not repeat it: implement the part that is missing. If the whole request is already satisfied, make no change and report that, citing the code that satisfies it.
