Run-level execution regime.
:async interprets effects immediately. {:bsp, opts} buffers actor effects
until barrier/1, allowing the same actor implementation to be replayed under
bulk-synchronous execution. {:bounded_async, k} permits each actor at most
k command envelopes ahead of the least advanced active actor. Idle active
actors deliberately hold back faster peers; completion removes a participant.
A command envelope is one update regardless of its number of effects.
Priority mode orders the currently pending envelopes by the supplied key;
it cannot order against arrivals that have not happened yet.
