v0.3.1

Release v0.3.1

✨ New Features

• SSH sessions have a Terminal type (TERM) select in Terminal settings (xterm-256color, xterm, vt100, vt220, linux, screen-256color, ansi); Telnet uses the same select. Pick vt100 for Cisco gear.
• "Save password" now works for servers that ask the password through keyboard-interactive (PAM, Cisco IOS/NX-OS): the saved password is reused on the next login and forgotten when rejected.

🔧 Improvements

• SSH connects to legacy network gear: diffie-hellman-group14-sha1, diffie-hellman-group-exchange-sha1, diffie-hellman-group1-sha1, aes*-cbc and hmac-sha1 are accepted after the modern defaults, so modern servers still negotiate modern algorithms.
• The SFTP channel is opened at login: the session banner shows "✗ SFTP browser (not offered by the server)" and "✗ Follow terminal folder (needs SFTP)" on servers without SFTP, and the sidebar no longer switches to a failing SFTP page.
• Session banner indented by 4 columns; the "Session stopped" rule is drawn with red ASCII dashes.
• New icon for the User sessions root folder.
• Release: the Windows artifacts always ship; the end-to-end receipt only decides whether they are marked preview.

📚 Documentation

• README rewritten for new users.
