Remove console.log statements from pubsub module

Problem

The server/lib/broadcast/pubsub.js module contains console.log statements that output to stdout during normal operation:

📥 Client ${clientId} subscribed to "${channel}"
📤 Client ${clientId} unsubscribed from "${channel}"
📣 Published to "${channel}" (0 subscribers)
📣 Publishing to "${channel}" (${subscribers.size} subscribers)

Libraries should not log to console by default because:

1. Pollutes application output - Mixes framework noise with application logs
2. No user control - Can't filter, format, or redirect these logs
3. Production overhead - Unnecessary I/O in production environments
4. Not actionable - The "0 subscribers" case is valid behavior (fire-and-forget), not an error

Expected Behavior

api-ape should be silent by default. Users who want visibility into pub/sub activity can add their own logging in handler functions.

Proposed Solution

Remove all console.log statements from pubsub.js (and any other modules with similar logging).

Files Affected

• server/lib/broadcast/pubsub.js
• server/socket/send.js (has binary registration logs)
