aider: Added the `connectToRELPServer` method to establish a TCP connection to the RELP server.

# Aider chat conversation:

USER: ../relp_handler.go:71:18: r.connectToRELPServer undefined (type *RELPHandler has no field or method connectToRELPServer)

ASSISTANT: It seems like the `connectToRELPServer` method is missing in the `RELPHandler` struct. Let's add this method.

Here is the *SEARCH/REPLACE* block:

relp_handler.go
```go
<<<<<<< SEARCH
func (r *RELPHandler) Startup() error {
	var err error
	r.conn, err = r.connectToRELPServer()
	if err != nil {
		return fmt.Errorf("Failed to establish TCP connection: %v", err)
	}
	go r.receiveEventsFromChannel()
	go r.processFailedEvents()
	go r.watchDirectoryForFailedEventFiles()
	return nil
}
=======
func (r *RELPHandler) connectToRELPServer() (net.Conn, error) {
	conn, err := net.Dial("tcp", r.relpServerURL)
	if err != nil {
		return nil, err
	}
	return conn, nil
}

func (r *RELPHandler) Startup() error {
	var err error
	r.conn, err = r.connectToRELPServer()
	if err != nil {
		return fmt.Errorf("Failed to establish TCP connection: %v", err)
	}
	go r.receiveEventsFromChannel()
	go r.processFailedEvents()
	go r.watchDirectoryForFailedEventFiles()
	return nil
}
>>>>>>> REPLACE
```

This block adds the `connectToRELPServer` method which establishes a TCP connection to the RELP server and returns the connection.
