systemprompt-analytics 0.67.0

//! Top-line dashboard metrics across all analytics domains.
//!
//! [`OverviewAnalyticsRepository`] reads the headline counts shown on the
//! analytics overview — conversations, agent/task activity, AI requests,
//! tool executions, sessions, and cost — each scoped to a time window.
//! Request, tool and task figures come from the hourly rollups, so a window
//! is widened to whole UTC hours at its start: every hour that begins before
//! `end` and does not end before `start` counts in full.
