Write a bot to scrape recent papers for potential new data/sources

Have a bot that scrapes the arxiv or ADS to find relevant papers, look for source matches, identify new data, open a pull request with new data suggestions.

Start by comparing the arXiv and ADS sources named in the issue and determine how relevant papers and source matches should be identified. No repository files or tests are named, so locate the bot entry point and existing data workflow first. Done means the bot finds relevant papers, identifies new data suggestions, and opens a pull request containing them.
