In the Inspector, log messages from the server were not being displayed.

modelcontextprotocol/inspector#184

The user who created the issue provided a python test server to send dummy messages, but I expected that the 'everything server' would be exercising this capability, but it wasn't. So I decided to add that functionality at the same time as fixing the inspector.

In src/everything/everything.ts
 - add logsUpdateInterval
 - use setInterval to send a random-leveled log message every 15 seconds
