doc(readme): Add options for verbose and debug log levels

This commit adds options for using verbose and debug log levels in the server and client. The `README.md` file has been updated to include instructions on how to use these log levels. Now, users can run the server with verbose logs using `cargo run -p server -- -v`, or with debug logs using `cargo run -p server -- -d`. Similarly, they can run the client with verbose logs using `cargo run -p client -- -v`, or with debug logs using `cargo run -p client -- -d`.
