Move agent-run orchestration from the legacy supervisor path into the new agentrun worker/service package and wire it through coredata, server, policies, and GraphQL resolvers. This consolidates run lifecycle handling around lease-aware workers and aligns API surface with the new agent-run domain model so reviewers can follow one coherent execution path.
