initial agent-mgr: app builder platform MVP
Go API server + Preact UI + Claude Code adapter. - App-centric model (ideas, not repos) - AgentProvider interface for multi-agent support - K8s pod lifecycle for sandboxed agent sessions - Gitea integration (create repos, push branches) - WebSocket streaming for live session output - Woodpecker CI/CD pipelines (kaniko build + kubectl deploy)
