overview.rs

//! Dashboard overview rolling up every analytics domain into one snapshot.
//!
//! [`OverviewArgs`] selects the time range; [`OverviewOutput`] aggregates the
//! per-domain metric cards (conversations, agents, requests, tools, sessions,
//! costs), comparing each against the immediately preceding period of equal
//! length to derive change percentages. Supports CSV export of the rolled-up
//! row.
