- Live remote-stack logs over a WebSocket proxied through the central app to
the agent (/ws/agent-logs/{agent}/{stack}); agent gains a WS log endpoint.
- Deploy to a remote host from the UI: host selector in the New Stack editor
and template dialog; templates instantiate onto an agent via the proxy.
- Network attach/detach: expandable inspect view per network with
connect/disconnect + container picker; GET /{id}/containers, POST connect/disconnect.
- Remove dead pages/Placeholder.tsx.
