✨ What's New & Highlights

📊 SFTP Transfer Queue & Live Progress Drawer

• Real-Time Transfer Metrics:
  • Sliding bottom drawer tracking all active, completed, and cancelled downloads & uploads.
  • Live progress bars, transfer speeds (KB/s, MB/s), elapsed time, and ETA calculations.
  • Real-time active transfers count badge pinned to the bottom status bar with 1-click toggle.
• In-Flight Cancellation:
  • Cancel any ongoing download or upload immediately with context cancellation, instantly freeing network I/O and cleaning up partial local files.
• Native OS Reveal:
  • "Show in Folder" action on completed downloads reveals the file directly in your native OS file manager (Windows Explorer, macOS Finder, Linux xdg-open).
• Tab Filtering & History Management:
  • Filter transfers across All, Active, and Completed tabs with 1-click history cleanup.

💓 Proactive SSH Keep-Alive & Auto-Reconnect Engine

• OpenSSH Heartbeat Probes:
  • Periodic keepalive@openssh.com global requests (default every 20s, configurable) with a 5s probe timeout to prevent idle connection drops behind NAT/firewalls.
• Accurate Drop Detection:
  • Distinguishes intentional user disconnects (Session.Close) from unexpected network drops (Session.MarkDropped).
• Contextual Reconnection Banner:
  • Top floating banner with live countdown ("Reconnecting in 3s... Attempt 1/5"), exponential backoff, and 1-click "Reconnect Now" action.
• Seamless Session Revival:
  • In-memory cached session credentials allow reconnection without re-prompting for credentials.
  • Automatically restores active port forward tunnels upon reconnect without altering the session ID, preserving open editor tabs.
• Configurable Settings:
  • New Advanced Options in Connection Profile dialog to customize keep-alive interval (seconds) and toggle auto-reconnect.

⚡ Instant 0ms Workspace Search & Quick Open Caching (Ctrl+P / Cmd+P)

• In-Memory File Cache & Deduplication:
  • Workspace files are cached in memory per session. Opening Quick Open is now instantaneous (0ms latency) without triggering repeated SSH requests.
  • Concurrent search requests are deduplicated so rapid opens share the same promise rather than flooding the remote server.
• 60fps Client-Side Fuzzy Search:
  • Keystrokes no longer dispatch heavy remote find commands; filtering runs locally at 60fps with multi-word scoring, exact matching, and recency ranking.
• Manual Refresh Trigger:
  • Added a 1-click "Refresh workspace index" button (RefreshCw) for updating the file cache when server files change.

🛡️ Robust Connection Teardown & Non-Blocking SFTP I/O

• Never-Hanging Disconnect:
  • Disconnect() now terminates cleanly with a safety timeout, ensuring the app never freezes or becomes stuck when dropping an unresponsive or broken connection.
• Fine-Grained SFTP Concurrency:
  • Released client mutexes during streaming downloads, uploads, and directory walks, preventing SFTP operations from blocking UI requests.
• Explorer Disconnect Action:
  • Added a dedicated "Disconnect" button directly on the Explorer error card when sessions drop, ensuring you are never trapped.

🖱️ File Tree Context Menu Three-Dots Fix

• Three-Dots Dropdown Trigger:
  • Fixed an issue where left-clicking the three-dots button (•••) on file and directory items dismissed the dropdown menu immediately.
  • Isolated pointer and click event propagation from parent row actions.

⚡ Core Engine Upgrades

• Vite 8 Upgrade:
  • Upgraded frontend build pipeline to Vite 8.3.4, yielding ~4x faster compilation times (~1.2s).
