feat: Implement live visitor count and Timmy greeting (#8 )

Fixes #8 - Added visitorCount to WorldState and implemented increment/decrement functions. - Updated WebSocket connection/disconnection handlers in events.ts to manage visitor count, broadcast events, and trigger Timmy greetings/farewells. - Implemented generateVisitorGreeting and generateVisitorFarewell in agent.ts to create personalized messages. - Modified websocket.js to listen for visitor_count events and pass them to ui.js. - Updated ui.js and index.html to display the live visitor count with responsive design.
