//! SSH jump host (ProxyJump) implementation for bssh
//!
//! This module provides SSH jump host functionality compatible with OpenSSH's ProxyJump (-J) option.
//! It supports connecting through one or more intermediate SSH servers (jump hosts/bastions) to reach
//! the final destination host.
//!
//! # Features
//! * OpenSSH-compatible -J syntax: `user1@jump1:port1,user2@jump2:port2`
//! * Single and multi-hop jump host chains
//! * Per-host authentication (different methods for each jump)
//! * Connection reuse for multiple operations
//! * Automatic retry with exponential backoff
//! * Integration with existing host verification and authentication
//!
//! # Rate Limiter
//!
//! The rate limiter has been moved to `crate::shared::rate_limit` to enable
//! code reuse between the bssh client and server implementations. This module
//! continues to re-export it for backward compatibility.

// Keep the rate_limiter module for backward compatibility but it now re-exports
