//! Compile-time extension framework for systemprompt.io.
//!
//! Built on the [`inventory`] crate, this crate lets extension authors
//! declare schemas, API routes, scheduled jobs, and provider
//! implementations using the [`Extension`] trait and the
//! [`register_extension!`] macro. The runtime collects every registration
//! at startup, validates dependencies, and merges the resulting wiring
//! into the host application.
//!
//! # Authoring an extension
//!
//! ```ignore
//! use systemprompt_extension::prelude::*;
//!
//! #[derive(Default)]
//! struct MyExtension;
//!
//! impl Extension for MyExtension {
//!     fn metadata(&self) -> ExtensionMetadata {
//!         ExtensionMetadata { id: "my-ext", name: "My Extension", version: "0.1.0" }
//!     }
//! }
//!
//! register_extension!(MyExtension);
//! ```
//!
//! # Module map
//!
//! - [`metadata`], [`router`], [`migration`] — value types describing the
//!   extension surface.
//! - The `Extension` trait and the [`register_extension!`] macro form the core
//!   extensibility contract.
//! - [`typed`] — compile-time-checked sub-traits (`SchemaExtensionTyped`,
//!   `ApiExtensionTyped`, ...).
//! - [`registry`] / [`typed_registry`] — runtime stores of registered
//!   extensions.
//! - [`builder`] — fluent builder that enforces dependency ordering at compile
//!   time.
//! - [`capabilities`] — `Has*` capability traits and the [`CapabilityContext`]
//!   composition helper.
//! - [`hlist`] — heterogeneous-list type machinery used by the dependency
//!   typestate.
//! - [`error`] — typed error enums ([`LoaderError`], [`ConfigError`]) raised by
//!   the registry and builder.
//!
//! # Feature flags
//!
//! This crate has no Cargo features; everything compiles into every build.
