v3.5.0.0 - Import/Export/Arrange Scripts and UI Improvements

🎉 New features

• Search - filter scripts by name with a new search box
• Drag-to-reorder - reorder scripts via a drag handle
• Export - export all scripts as a JSON backup, or export any individual script as a standalone .js file
• Import - import scripts from a JSON backup; detects name collisions and asks whether to import duplicates or only the new ones
• Unsaved changes warning - prompts before closing/refreshing the tab if you have unsaved edits

✨Improvements

• New scripts now auto-expand and focus the name field for immediate editing
• Empty-state messaging when there are no scripts (or no search matches)
• Fixed duplicate event-listener registration on repeat page views
