Added cluster/node topology section referencing all 5 Proxmox nodes and
clarifying that the contract is infrastructure-agnostic — defines the who
and when, not the where.
Defines when to delegate, worker selection matrix, verification protocol,
kanban board, and failure handling. Addresses the context overflow and
iteration exhaustion issues where the manager was doing all work itself
instead of delegating to the 6 worker profiles.
