chore(catalog): sign app-catalog — BotFights 1.2.9, Cashu primary UX + anonymous-bot staking

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): 1.2.8 -> 1.2.9.
