Removed llms-full.txt

The llms-full.txt endpoint has been removed from Fern Docs sites. This file concatenated every page into a single document, but in practice it saw little use compared to llms.txt and individual .md page URLs. It also exceeded most model context windows and added significant serving overhead on every request.

If you previously relied on llms-full.txt, use llms.txt to discover page URLs and fetch individual pages as needed.
