meerkat-mob 0.8.1

//! Mob runtime: actor, builder, handle, and primitives.
//!
//! The mob runtime uses an actor pattern where all mutations (retire, wire,
//! unwire, etc.) are serialized through a single command channel. Spawn
//! provisioning is parallelized, then finalized through the same actor.
//!
//! The public `MobHandle` surface is being consolidated behind one top-level
//! machine command seam. Mutations, event surfaces, and diagnostics are routed
//! through that seam. Canonical member lifecycle projection remains an
//! intentional lock-free read path over shared roster/session truth so
//! `Retiring` and supersession windows stay observable even while disposal work
//! is in flight.
