//! Module: sns::report::neurons_cache::refresh::run
//!
//! Responsibility: run SNS neuron cache refresh operations.
//! Does not own: page collection internals, snapshot publishing details, text rendering, or CLI parsing.
//! Boundary: resolves the target SNS, acquires the refresh lock, and wraps attempt lifecycle hooks.
