//! Addon ecosystem: community extensions for lean-ctx (#858).
//!
//! An **addon** packages an external MCP server (+ metadata) behind a small
//! [`lean-ctx-addon.toml`](manifest) manifest, so a third-party tool plugs into
//! lean-ctx's MCP gateway with a single `lean-ctx addon add` — no fork, no
//! recompile. Addons are user-global and reuse the gateway trust model
//! (`[gateway]` is global-only and opt-in; see [`crate::core::gateway`]).
//!
//! Layers:
//! - [`manifest`] — the `lean-ctx-addon.toml` contract (also the registry entry shape).
//! - [`registry`] — the curated catalog (bundled, with optional user override).
//! - [`store`] — what is installed locally (`<data_dir>/addons/installed.json`).
//! - [`install`] — wires an addon into the gateway and records it in the store.
