Hollow: A Modular, Focused Workspace - new features, most notible being focused instances.

Introduced Character Sheets, Vault Storage for reusable assets, and required Realm folder locations to improve portability and backups. Added Focus Mode for distraction-free, full-canvas cards, Tool Insights popups, and seamless auto-updates. The UI was fully redesigned with a minimalist, panel-driven layout, the canvas migrated to Gridstack for better responsiveness, and code themes and icons are now dynamic, cached on demand, and managed through the Vault system.
