rustango 0.44.0

Django-shaped batteries-included web framework for Rust: ORM + migrations + auto-admin + multi-tenancy + audit log + auth (sessions, JWT, OAuth2/OIDC, HMAC) + APIs (ViewSet, OpenAPI auto-derive, JSON:API) + jobs (in-mem + Postgres) + email + media (S3 / R2 / B2 / MinIO + presigned uploads + collections + tags) + production middleware (CSRF, CSP, rate-limiting, compression, idempotency, etc.).

//! Model Context Protocol (MCP) server — expose rustango apps to external
//! ML agents over JSON-RPC 2.0 / Streamable HTTP.
//!
//! Epic #1013. **Slice 1 (#1014)** ships the foundation: the `src/mcp/`
//! module + `mcp` Cargo feature, the JSON-RPC 2.0 envelope, the
//! Streamable-HTTP transport (`POST` request / `GET` SSE notification
//! stream), and the `initialize` + `ping` methods. No auth, tools,
//! skills, prompts, or resources yet — those land in Slices 2–6.
//!
//! ## Mounting
//!
//! ```ignore
//! // Single-tenant:
//! let api = axum::Router::new().nest("/mcp", rustango::mcp::router(pool));
//! rustango::manage::Cli::new().api(api).run().await?;
//!
//! // Multi-tenant (tenancy Builder injects the TenantContext):
//! let api = axum::Router::new().nest("/mcp", rustango::mcp::tenant_router());
//! ```
//!
//! An MCP client then completes the lifecycle handshake — `initialize`
//! (capability negotiation) followed by a `notifications/initialized`
//! ack — and can `ping` to check liveness, all over the single `POST`
//! endpoint.
