releases/app-catalog.json regenerated and signed by the release-root key (did:key:z6MkkidEnEpo6qHMCNSZoNKWtvQvxq3whnaME9wGgEFhq7ur). botfights is the only content change vs the previously-published catalog (verified structurally — all other 65 apps unchanged): 1.2.7 -> 1.2.8, fixes broken profile pictures (CSP img-src) and makes the AI-answer feature discoverable by default.
