docs: name the editions Shannon, Pro, Enterprise and Community Program

Drop "Shannon Open Source" and "the Keygraph platform" as product names.
The open-source project is Shannon (Shannon OSS where a contrast helps),
and the commercial editions are Keygraph Pro and Keygraph Enterprise, plus
the Community Program. The one retired-names line now maps Shannon Lite to
Shannon and Shannon Pro to Keygraph Pro. Also covers the npm README, the
coverage and safety docs, llms.txt and the regenerated llms-full.txt.
