Sort & Filter

As an AI platform user, in order to efficiently find the information I'm looking for, I would like to be able to sort and filter search results (on search/category pages) by criteria and attributes that are relevant/assigned to the content (use cases and resources content).

Use case attribute/tag management is addressed in a separate story.

Features & Details:

1. On search results only, a content category/type filter is available to filter the results by use cases or by AI resources
2. On search results and category pages, content attributes/tags are displayed as filters
3. Selecting attributes/tags filters the results based on the selected attribute/tag
4. Search results are sorted by relevancy by default
5. Content on category pages is sorted by newest to oldest by default
6. Suggested sort options: chronological, alphabetical, programmatic, scale, status, location

No files, tests, or entry points are named; start by locating the search results and category-page implementation. Confirm how use cases, AI resources, attributes, and tags are represented, then verify the requested filters and default sort orders against the six listed behaviors.
