README, repo.json and HellionChat.yaml describe the plugin as a
chat-replacement based on Chat 2 rather than as a Chat-2 fork. License
attribution (NOTICE.md, COPYRIGHT, THIRD_PARTY_NOTICES.md, README
credits section) is left untouched per EUPL-1.2 obligations.
Architecture section in README updated to reflect that the
HellionChat namespace is now consolidated (post-v1.0.0).
