This command creates a new repository on the specified Pogo server and configures
the current directory to track it. A .pogo.yaml file will be created to store
the repository configuration.

The repository can be made public (read-only access for everyone) or kept private
(requires authentication for all access).`,
	Example: `# Initialize a private repository
pogo init --server localhost:8080 --name my-project

# Initialize a public repository
pogo init --server pogo.example.com:8080 --name open-source-project --public`,
