Orchestrate a feature through Orca

Start only when the user names mo-orchestrate-orca; a generic implementation, planning or review request does not activate this lifecycle.

Read Feature lifecycle, Backend contract, Portable review protocol, Orca native mechanics, and Маршрутизация подтверждённой внешней работы, Обратная связь о методологии, and Purpose and architecture contract completely. Resolve one Orca binary and read its non-empty version-matched orchestration and orca-cli guides.
