//! Generate a string session for serverless deployments.
//!
//! Logs in once via a local session file, exports a compact session string,
//! then prints it. Store the string in SESSION_STRING and use it with the
//! serverless_userbot example to connect without a session file.
//!
//! Run:
//!   cargo run --example string_session_gen
//!
//! Keep the string private. It gives full access to your account.
