//! Tauri commands for playback reporting operations
//!
//! TRACES: UR-025, UR-019 | IR-015, JA-010, JA-011, JA-012 | DR-028
//!
//! These commands provide frontend access to the Rust playback reporting system,
//! replacing the TypeScript implementation with native Rust reporting.
//!
//! Commands are registered but not yet called from the frontend.
//! Dead code warnings are suppressed until frontend migration is complete.
