Problem

The WhatsApp channel health monitor restarts the socket when no events arrive for >30 minutes (staleEventThresholdMs defaults to 1,800,000ms). During idle periods (e.g., nighttime), this causes ~38 unnecessary socket restarts per day.

Root Cause

In gateway-cli-*.js, resolveTimingPolicy() falls back to 18e5 (30min) when deps.timing?.staleEventThresholdMs is undefined. The main health monitor call site (startChannelHealthMonitor()) only passes channelManager and checkIntervalMs — no timing object.

Impact

• ~38 restarts/day (1-2/hour), evenly distributed
• 0 message delivery failures observed (restarts are seamless, 2-5s reconnect)
• Cosmetic log noise, unnecessary reconnection churn

Requested Change

Expose staleEventThresholdMs as a configurable option, e.g.:

{
  "gateway": {
    "channelHealthCheckMinutes": 5,
    "channelHealthMonitor": {
      "staleEventThresholdMs": 7200000
    }
  }
}

Suggested default: 2 hours (7,200,000ms) for long-socket channels like WhatsApp.
