bitrouter (library)

Assembly layer: turns a [bitrouter_sdk::config::Config] into a running [bitrouter_sdk::App], and carries the management-command logic.

Foreground custom hosts register typed capabilities through [bitrouter_sdk::extension::ExtensionApi] and [host::serve_with_extensions], sharing the product's complete service and management lifecycle. Embeddings that own their listeners can use [assemble::build_app_with_extensions]. Router configuration explicitly binds capabilities; host assembly retains execution and receipt ownership. The default binary does not link concrete extension implementations. The SDK never depends back on this product host; main.rs is the CLI entry point.
