//! Queue dashboard subcommand - aggregated analytics for GUI clients.
//!
//! Responsibilities:
//! - Load queue, done, and productivity data once.
//! - Delegate to reports::dashboard for aggregation.
//! - Emit a single JSON payload combining all dashboard sections.
//!
//! Not handled here:
//! - Report data structures (see reports/dashboard.rs).
//! - Queue file loading (see crate::queue).
//!
//! Invariants/assumptions:
//! - Dashboard only supports JSON output (designed for GUI consumption).
//! - Productivity stats are optional (may not exist for new projects).
