//! Module: sns::report::proposals_cache::refresh::run
//!
//! Responsibility: expose complete SNS proposal snapshot refresh entry points.
//! Does not own: shared locking and attempt mechanics, cache publication, or text rendering.
//! Boundary: adapts proposal collection and publication to the shared refresh lifecycle.
