Implements cloud-to-workspace heartbeat mechanism to prevent Fly.io from idling machines that have active agents running. Problem: Fly.io uses request-based concurrency tracking. When Claude is running but no user has the dashboard open, there are no inbound HTTP requests, so Fly may idle the machine. Solution: - Add /keep-alive endpoint on workspace dashboard server - Create WorkspaceKeepaliveService that pings workspaces every 60s - Only pings workspaces that have online daemons with active agents - Inbound ping counts as activity for Fly's idle detection The service: - Queries all running workspaces with public URLs - Checks each workspace's daemons for online status and active agents - Pings /keep-alive endpoint which responds with active agent count - Stops pinging when no agents are active (allowing normal idle)
