fix(plugin): skip delivery prompt for unit-based change strategy

With unit strategy, each unit already gets its own PR during
construction. The intent-level delivery prompt ("How would you like to
deliver?") made no sense in that context. Now the delivery prompt is
gated on change strategy — skipped entirely for unit strategy, shown
only for intent strategy or hybrid intents with non-unit units.
