Agent Skills: delimit

Delimit a large body of work into right-sized execution units before its method is conducted. Searches for the cut-set over an external work-breakdown structure such that each unit fits one execution span, every cut falls at a natural joint, and coverage is complete with no work orphaned — then emits a WorkUnitMap that references the WBS without owning it, ready to flow into /conduct. Type: (GranularityUnderdetermined, Hybrid, DELIMIT, ExternalWBS × ExecutionHorizon × ContextLifecycle) → WorkUnitMap. Alias: Diairesis(διαίρεσις).
