v0.21.0

• Workspaces: group your projects into workspaces, and give each agent and paired phone access to only the workspaces it needs
• Dev Template: better task routing to Coders and clearer Coder instructions, with automatic cleanup for sub-agents and automatic compact for the Epic Manager and Code Reviewer
• Subscribers: new Terminate Session and Delete Agent actions
• Agents: the Agents page is now configuration-only — launch, restart, and terminate live in Chat
• Devices: optional local alias for paired devices, messages from a phone say which device sent them, and logging out no longer resets a phone's access
• Startup: fixed a Linux startup hang and false timeout caused by slow DNS (GitHub #18)
• Mobile app 1.7.0
