Replaced the SSH library + IO thread + intermediate PTY bridge with vte_terminal_spawn_sync(). This eliminates the broken terminal behavior (backspace, Ctrl+C, copy/paste, bash completion) caused by the intermediate PTY with no process on the slave side. - SshTerminal now spawns 'ssh' as a VTE subprocess - Removed libssh dependency from terminal (still used for key validation) - Removed IO thread, manual PTY creation, and thread synchronization - VTE now handles all terminal I/O, line discipline, resize, etc. - Password saved: uses sshpass -e with SSHPASS env var if available - Password not saved: ssh prompts interactively in the terminal - Removed show_password_dialog (no longer needed) - Simplified connect flow in ssh_client.cpp
