OpenMetaConvention

The self-describing open_meta convention, returned by [describe_open_meta] and rendered by the
CLI resource describe-open-meta command, the MCP describe_open_meta tool, and
GET /api/schema/open-meta. All three surfaces share this type so the guidance can never drift
between them.
