Crate standout_dispatch

Expand description

Command dispatch and orchestration for clap-based CLIs.

Routes parsed ArgMatches to a Handler, running pre-dispatch, handler, post-dispatch, and post-output hooks around it, and returns typed HandlerResult data — presentation stays with the consuming framework. A handler adapter takes (&ArgMatches, &CommandContext) and returns serializable data, so application logic stays reusable outside a CLI.

CommandContext carries two kinds of injected state: app_state is immutable and app-lifetime (database, config, API clients), built once and shared via Rc; extensions is mutable and per-request, set by pre-dispatch hooks for things like a resolved user session.
