Support Cascading Parsing of Related Links When Uploading URL Resources

Is your feature request related to a problem? Please describe.
I'm often frustrated when uploading a URL as a resource because I have to manually find and add related links embedded within that URL. This is especially inconvenient when working on academic papers or research projects where multiple related references are linked together.

Describe the solution you'd like
I would like an option to enable cascading parsing of the uploaded URL, so that the system automatically detects and extracts related or associated links contained within the main URL. This would streamline the process of gathering all relevant resources in one step.

Describe alternatives you've considered
Currently, I manually open the URL and copy each related link one by one, which is time-consuming and error-prone. Another alternative is using external web scraping tools, but integrating this feature directly would be much more efficient.

Additional context
This feature would be very helpful in academic and research scenarios where papers often reference multiple related works through hyperlinks. A screenshot or example of a URL with multiple embedded links could illustrate the use case better.

The issue names no files, tests, or entry points. Start by locating the URL resource upload and parsing flow, then clarify how cascading should be enabled, which links qualify, and what completion behavior should be tested.
