v1.7.0

🔖 R-Shell 1.7 — Stable Sessions

This release brings long-lived connection reliability: SSH keepalive prevents servers from silently dropping idle sessions, and the PTY terminal now detects dropped connections gracefully instead of silently replacing the shell. A new lazy-loading directory tree, improved file browser toolbar, and robust path quoting round out the update.

Added

• 🌳 Directory Tree: New lazy-loading, expandable directory tree panel in the integrated file browser for fast folder navigation without changing the main view
• 🔌 SSH Keepalive: Client-side SSH keepalive now runs every 60 seconds (3 missed replies triggers clean disconnect), preventing SSH servers from silently timing out idle connections after hours of inactivity

Changed

• 🖥️ File Browser Toolbar: Enhanced integrated file browser UI with an improved toolbar layout, clearer action grouping, and better visual hierarchy

Fixed

• 🐛 Path Quoting: File listing and stat commands now correctly quote paths containing apostrophes, spaces, and other shell special characters — fixes errors browsing directories with unusual names
• 🔄 PTY Session Loss Detection: After a session is established, a dropped SSH connection now displays [SSH session lost. Use right-click → Reconnect] instead of silently spawning a fresh shell with lost state
• ⚡ Reconnect Retry: Implemented cancellation-aware exponential backoff for PTY reconnect attempts; permanent failures (connection not found) now fail fast instead of burning all retry attempts uselessly
