Subject: [PATCH] fix: lower websocket session ended log severity from Error to
 Warn in pkg/ws/client.go
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

# Description

In `pkg/ws/client.go` at line 122 within `Client.Run`, session termination errors returned by `c.connectAndServe(ctx)` are logged at `Error` severity with `c.logger.Error("websocket session ended", "err", err)`. During transient disconnections 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)`), retaining full visibility into session terminations without incrementing error log metrics, while unrecoverable errors remain logged at error level.

```
Change the log severity of expected or transient session endings from c.logger.Error to c.logger.Warn or c.logger.Info in pkg/ws/client.go line 122. During routine connection renegotiation or relay disconnects, the client successfully reconnects via exponential backoff; logging at Error level produces benign alert firings under ForagerServiceLogErrors. Regression check: verify that normal connection termination does not increment container_log_messages_total{level="error"} while unrecoverable errors remain logged at error level.
