✨ What's New & Highlights

🛡️ Robust Error Handling & Crash Protection

• React Sectional <ErrorBoundary>:
  • Integrated error boundaries around all major workspace zones (Side panels, Explorer, Editor, Settings, and Release Notes).
  • Component crashes or syntax errors in editors no longer cause white-screen failures.
  • Includes user-facing recovery controls: Reload View, collapsible Technical Details stack viewer, and Full Restart.
• Centralized Error Parsing & Actionable Hints (formatErrorMessage):
  • Automatically translates cryptic Go, SSH, SFTP, and OS errors into structured { title, message, hint, raw } objects across 13 categories:
    • Authentication Failures: Clear advice on username, password, or key passphrases.
    • Connection Refused: Guides users to check sshd status, listening ports, and firewall rules.
    • DNS / Host Resolution: Pinpoints DNS lookups and typos.
    • Connection Timeouts & Network Unreachability: Actionable hints on server reachability and VPN routing.
    • Host Key Verification & Security Warnings: Explicit guidance on untrusted or changed host keys.
    • SFTP Permissions & Missing Files: Clear Linux file permission (chmod/chown) hints.
    • Concurrent File Modification: Interactive conflict warnings with "Overwrite anyway" options.
    • Buffer Limits: Guards on files exceeding editor size limits.
    • Disconnected Sessions: Contextual prompts to reconnect.
• Inline Connection Error Banners:
  • Replaced fleeting toasts in ConnectDialog with persistent inline error alerts above action buttons, complete with troubleshooting hints and a toggleable raw technical details view.
• Remote Explorer Failure Recovery:
  • Replaced misleading "Directory is empty" states during SFTP failures with an explicit error screen and an inline Retry action.
• Go Backend Panic Prevention & Nil Safety:
  • Added centralized getSFTPClient in app.go with strict nil checks and session validation.
  • Added receiver and client nil guards across sftpclient.Client methods before mutex acquisitions.
