Add clone support across Action types and Command so commands can be safely registered or runner-bound without mutating the original instances. - clone BaseAction implementations across simple, composite, IO, prompt, file, HTTP, process, and signal actions - bind cloned commands in Falyx.add_command_from_command() and CommandRunner - preserve local never_prompt settings when cloning actions - rename shared runtime state from options to options_manager for consistency - seed root and execution option namespaces consistently - apply scoped root and namespace option overrides during routing and dispatch - improve namespace completion by delegating option suggestions to FalyxParser - enrich missing-value errors and error hints
