Worker Operator Bundle

Adds macOS and Windows Worker installer bundles for assigning approved jobs to a customer-owned machine. Worker can receive scoped tasks from Codex or Claude Code, run local tools and configured local LLM routes, report status, and keep private files and credentials on the workstation unless a configured tool intentionally calls an outside service. Requires customer-managed model/runtime setup, machine access, and review of each task; it is not a hosted compute service, not an LLM provider, and not a guarantee that every workflow is offline.
