Stop logging every Responses WebSocket event

[jif-oai]

Why

Every successful Responses WebSocket event currently produces three local log records: the full payload at TRACE, an OpenTelemetry log event, and an OpenTelemetry trace event.

On busy threads these records fill the 1,000-row log partition in seconds and cause continuous SQLite insert-and-prune churn.

What changed

• Stop logging each successful Responses WebSocket payload at TRACE.
• Stop emitting codex.websocket_event as OpenTelemetry log and trace events.
• Keep WebSocket event counters, duration metrics, response timing metrics, parsing, and error handling.
