Move agent-run orchestration from the legacy supervisor path into the new
agentrun worker/service package and wire it through coredata, server,

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.
