Optional minMinimum number of agents that must SUCCEED. Under parallel the default
is 0 (no floor); under panel the seats counted are the healthy ones
(those that returned text) and the default is 2 for a roster of two or more.
Optional minMinimum number of DISTINCT providers among the successful agents
(default 0 = no floor). Counted from each result's resolved provider.
Optional minpanel only: minimum number of DISTINCT known vendors (the organization
that trained the model) among the healthy seats. An unknown vendor never
counts; a pre-built seat never counts.
Optional onWhat a shortfall does: 'error' (default) throws
AgencyQuorumError before synthesis; 'proceed' logs a warning
and synthesizes anyway. Under panel, zero healthy seats throws whatever
this says.
