DevMate 4.0.4

• The address of a quick tunnel ends in a key, new with every start: https://<name>.trycloudflare.com/mcp/<key>. Only the whole address opens anything; the host name alone, which anyone watching DNS can see, answers "not found". devmate doctor prints the address without the key. After updating, give your client the new address from devmate mcp-url.
• Through a quick tunnel DevMate answers in plain JSON, for clients of both protocol generations and without progress messages: Cloudflare does not carry event streams through quick tunnels. npm run smoke:quick-tunnel checks this against a real tunnel.
• One call waits at most 50 seconds (shell_run, process_read, agents_delegate, agents_result) and one text result stays under 140,000 characters, which fits the limits of ChatGPT and Claude. Longer work keeps running and is asked about again; a result that would be larger says where it was cut and how to ask for less. A page of workspace_read or of a diff holds 120,000 characters, a page of command output 128 KiB, a page of bytes 96 KiB.
• VS Code says when a route from the cloud was checked end to end under a new address, with the address one click away, and when a route stays broken; the status bar tells connecting, reconnecting and a failed check apart. Copying the address of a quick tunnel that has none yet no longer hands out the local one (also devmate mcp-url and Obsidian).
• The README says which ChatGPT and Claude plans let a connector you add change things and which only read, with the sources.
• npm run check fails when a file names an earlier version of DevMate or an option that was taken out.
