//! Productivity stats tracking for task completions, streaks, and velocity metrics.
//!
//! Responsibilities:
//! - Track daily task completions and calculate streaks
//! - Record milestone achievements (10, 50, 100, etc.)
//! - Calculate velocity metrics (tasks per day/week)
//! - Persist stats to `.ralph/cache/productivity.jsonc`
//!
//! Not handled here:
//! - Queue/task management (see `crate::queue`)
//! - Notification delivery (see `crate::notification`)
//! - Celebration rendering (see `crate::celebrations`)
//!
//! Invariants/assumptions:
//! - Stats file is JSON with schema version for migrations
//! - Timestamps are RFC3339 format
//! - All operations are atomic (read-modify-write with file locking)
