// Package resource provides CLI commands that map directly onto
// go-micro's core interfaces — registry, broker, store, and config.
//
// Each interface gets its own top-level command with verbs that mirror
// the interface methods, so the framework's building blocks are
// inspectable and manipulable from the terminal:
//
//	micro registry list
//	micro broker publish <topic> <message>
//	micro store read <key>
//	micro config get <key>
//
// New resource commands are registered by appending to the commands
// slice in init — see registry.go, broker.go, store.go, config.go for
// the per-interface implementations.
