Save information about build node

Note

Store builder node CPU info in env_builds and plumb machine info from orchestrator/edge to handlers while TemplateManager.GetAvailableBuildClient now returns the builder instance.

• Database:
  • Add CPU machine info columns to public.env_builds (cpu_architecture, cpu_family, cpu_model, cpu_model_name, cpu_flags).
  • Update queries and generated models to read/write the new fields across build/snapshot/template queries.
• API/Handlers:
  • On build start (v1/v2), fetch builder node instance and persist its machine info into env_builds; use builderNode.NodeID where needed.
  • Layer file upload updated to accept builder node instance.
• Edge/Orchestrator:
  • Add machineInfo to edge.ClusterInstance with GetMachineInfo; populate during sync and on pool insert.
  • Introduce shared machineinfo package and replace local types in node manager.
  • Change TemplateManager.GetAvailableBuildClient to return *edge.ClusterInstance; update delete fallback and callers accordingly.
