/**
 * ProcessTaskAdapter, bridges ProcessManager background processes into the

 *
 * NOTE: This adapter writes directly to the Zustand store for performance,
 * bypassing TaskManager. Lifecycle validation is the caller's responsibility.
 * This is intentional, adapters are authoritative sources for their subsystem.
