fix(orchestrator): respect KG action template CLI tool in routing engine (#819)

When use_routing_engine is enabled, the RoutingDecisionEngine returns
both model and cli_tool from the KG route action template, but
spawn_agent() only extracted the model and discarded the CLI tool.

Also updates taxonomy model names from version-pinned to aliases
(haiku/sonnet/opus) so Claude CLI resolves to latest automatically.
