//! Model Context Protocol (MCP) server for aprender.
//!
//! Exposes the `apr` CLI as MCP tools for Claude Code, Cursor, Cline, and
//! other MCP clients over JSON-RPC 2.0 stdio transport.
//!
//! Spec: `docs/specifications/apr-mcp-server-spec.md`.
//! Protocol: MCP v2024-11-05 (<https://spec.modelcontextprotocol.io>).
//!
//! # Example
//!
//! ```no_run
//! # #[cfg(feature = "native")]
//! # fn main() -> anyhow::Result<()> {
//! let mut server = aprender_mcp::AprMcpServer::new();
//! server.run_stdio()?;
//! # Ok(())
//! # }
//! # #[cfg(not(feature = "native"))]
//! # fn main() {}
//! ```
//!
//! # Scope (M1–M3 shipped)
//!
//! - M1: `initialize` + `tools/list` + the `apr.version` stub.
//! - M2: 7 subprocess wrappers (`apr.validate`, `apr.tensors`, `apr.bench`,
//!   `apr.qa`, `apr.trace`, `apr.run`, `apr.serve`) + FALSIFY-MCP-005/-007
//!   dispatcher gates + Draft-7 schema meta-validation.
//! - M3: `apr.finetune` (8th Phase-1 tool), `notifications/cancelled` →
//!   SIGTERM→SIGKILL for `apr.run`, `build.rs` codegen from
//!   `contracts/apr-mcp-tool-schemas-v1.yaml` for both `inputSchema`
//!   (`schemas::APR_<TOOL>_SCHEMA`) and tool-level `description`
//!   (`schemas::APR_<TOOL>_DESCRIPTION`, PMAT-514), and opt-in per-line
//!   `notifications/progress` for `apr.finetune` via
//!   `params._meta.progressToken` (FALSIFY-MCP-PROGRESS-001).
//!
//! M4 (in progress) promotes FALSIFY-MCP-003/-004 from surface tests to
//! real-model end-to-end; M5 ports the dispatcher to `pmcp = "2.3"` and
//! extends cancellation to `apr.serve`.
