Problem Description / Use Case

Hello!
First of all, I want to express my appreciation for the work and effort put into this project — it’s been a great experience using Seanime.

I’d like to suggest a feature that I believe would be quite helpful: the ability to filter and view tags associated with each library item, as well as support for more advanced filtering options when querying the library. This would make managing and navigating collections much more efficient, especially for larger libraries.

Thank you for considering this, and thanks again for your great work!

Proposed Solution

I've been working on implementing these features in a personal fork, which includes the following updates:

• GraphQL schema updates to support tag-related queries
• Minor changes to the Go internal API to enable these queries
• Frontend support: a simple tag display on the anime details page
• A tag filter in the detailed view for easier navigation
• An optional setting to split adult entries in the initial view

I’d be happy to share the changes or open a PR if the direction aligns with the project's goals. Let me know your thoughts!
