v0.13.6

Fixed

• Native mode update support - Update button now runs update.sh/update.ps1 in native mode
  • Auto-detects Docker vs native environment (checks /.dockerenv and /proc/1/cgroup)
  • Native mode spawns update script detached, allowing PM2 restart
  • Docker mode falls back to Watchtower with manual command modal if unavailable
• Duplicate update toast - Fixed "Update Available" toast appearing while already updating
  • Dismisses update-available toast immediately when clicking Update
  • Skips update check if update is in progress
  • Uses id: 'update-available' to prevent duplicate toasts
• Unified update endpoint - POST /api/version/update now handles both Docker and native modes
  • No longer requires separate /api/version/update/docker endpoint for Docker mode
  • Returns appropriate error message based on environment
