Detailed Description

Centralised event demultiplexer and dispatcher for managing I/O events.

EventDispatcher coordinates between the event detection mechanism (epoll) and register event handlers. It maintains a registry of handlers, waits for events to occur on monitored file descriptors, and dispatches events to appropriate handlers. This implements the core of the ClientHandler pattern for non-blocking, event-driven I/O.
