Promote Enterprise-Managed Authorization to stable
Move the extension from specification/draft/ to specification/stable/ to
indicate it is ready for use and has reference implementations. Update the
README to list stable and draft extensions separately, and update the
in-document status banner to match.

# MCP Authorization Extensions
The Model Context Protocol (MCP) specification is defined in the [main specification repository](https://github.com/modelcontextprotocol/modelcontextprotocol/tree/main/docs/specification). This repository contains **extensions** to the core protocol that define additional authorization mechanisms.
These extensions are:
- **Optional** - Implementations can choose to adopt these extensions
- **Additive** - Extensions do not modify or break core protocol functionality; they add new capabilities while preserving core protocol behavior
- **Composable** - Extensions are modular and designed to work together without conflicts, allowing implementations to adopt multiple extensions simultaneously
- **Versioned independently** - Extensions follow the core MCP versioning cycle but may adopt independent versioning as needed
## Extensions
### Stable
- [Enterprise-Managed Authorization](https://github.com/modelcontextprotocol/ext-auth/blob/main/specification/stable/enterprise-managed-authorization.mdx)
### Draft
- [Client Credentials](https://github.com/modelcontextprotocol/ext-auth/blob/main/specification/draft/oauth-client-credentials.mdx)
## Governance
This repository follows the [Model Context Protocol Governance](https://modelcontextprotocol.io/community/governance) process, with a dedicated set of maintainers for authorization extensions. See [MAINTAINERS.md](./MAINTAINERS.md) for the list of maintainers specific to this repository.
All decisions regarding authorization extensions follow the same governance model as the core specification, including:
- Specification Enhancement Proposals (SEPs)
- Community discussion and consensus building
- Maintainer review and approval
- Transparent decision-making
