The registry grew from 36 to 56 entries upstream. Add a detail file for
each new slug, researched against official sources: docs and repository
links, install commands, getting-started steps and a copyable agent setup
prompt.

Optional fields are filled only where they could be verified. CodeFronts
has no install mechanism so its install array is omitted; Rive, DiMAAC UI
and UI by Hampton have no reachable og:image and no public repository
respectively, so those fields are omitted rather than filled with a guess.
