`argent init` puts mcp config for Claude in a nonexistant "server" key

Basically what the title says. it puts this in the `.mcp.json` file: ``` "servers": { "argent": { "type": "stdio", "command": "argent", "args": [ "mcp" ], ... ``` but the key you need is "mcpServers.json" as far as I know. I [looked through the Claude Code docs](https://code.claude.com/docs/en/mcp) and didn't see any mention of a "servers" key.
