Enhanced Tagging & Filtering in Smart Topics

Introduce the ability to @tag other notes or create a separate #tag system for custom categorization.

Enable filtering within Smart Topics (Library Topics) by tags for deeper exploration.

• Use case: I’m learning about communication challenges and have 50+ notes, but I’d love to drill down further through visual, written, or verbal communication—currently, this isn’t possible.

Allow filtering of Smart Topics by chat vs. notes, providing a more structured way to navigate content.
