Block launches Buzz, combining chat, AI agents, and git hosting

Block (Jack Dorsey) shipped Buzz, positioned as a single tool combining team chat, AI agents, and git hosting — announced on Block's own engineering blog and picked up widely (364+ points on HN). Another entrant in the "AI-native workspace that also does version control" category alongside the coding-agent IDEs; worth watching whether the combination sticks or these stay separate tools that talk to each other.
