Vertical Tabs v0.18.4

🎉 What's New:

Tab and group customization: Personalize your workspace by customizing tabs and groups with custom titles, icons, and colors.
Mobile tab groups are back: You can now create tab groups on mobile again. This brings back the feature that was disabled in Obsidian 1.13.6, while still keeping Obsidian’s normal behavior (#239).
Introduced an event-based API for icon rendering and menu customization, making it possible to integrate with third-party plugins like Iconic and Iconize.

Fixed the issue where the open tab list may not update when Vertical Tabs is hidden (#240).
Fixed custom group titles being lost after reloading.
Fixed tab group order and sorting preferences not persisting after restart.
Fixed issue where settings were not being saved properly.
Resolved drag-and-drop behavior issues for tab groups.

Refactored and improved cache stores for better performance and maintainability.
Migrated from PersistenceManager to LocalStorageService, simplifying the codebase and improving data persistence reliability.
Improved drag-and-drop visual feedback for tree items.
Polished workspace customization and Mission Control View styling.
