//! `McpServerConfig` impl for the unified config's `McpConfig` section.
//!
//! Type definitions live in `ferridriver-config`. This module wires those
//! types into the runtime `McpServerConfig` trait so the MCP server can be
//! driven directly from a `ferridriver.toml` file with no custom Rust code.
