Community resource: systemprompt-template — Rust MCP governance runtime #821

Hi — wanted to share a community resource that might be worth linking in the README or ecosystem docs.

systemprompt-template is a production-grade Rust runtime for hosting and governing MCP servers. For developers using this SDK who want to build enterprise-ready infrastructure (not just a single server), it might be a useful reference.

Key features relevant to rust-sdk users:

• Uses the MCP protocol to host multiple servers with governance (RBAC, secret detection, rate limiting, audit)
• A2A orchestration built in alongside MCP
• Single binary deployment (~50MB), PostgreSQL only
• Rust 1.75+, 30-crate workspace

Would you consider adding it to the README under a "Community Projects" or "Examples" section? Happy to open a PR if that's preferred.
