- Break monolithic records.rs into commands/, output/, parsing/ modules - Add lib.rs with shared types (AppError, Car, BestCarRecord, etc.) - Replace Arc<Mutex<HashMap>> with DashMap for concurrent access - Add unified AppError enum with thiserror - Add configurable CLI paths (--my-cars, --cars-db, --times-dir, --tracks-db) - Add serde deserialization for Car struct - Add CSV escaping for fields with commas/quotes/newlines - Fix track name splitting: split_once -> rsplit_once for _a handling - Add integration tests, proptest property-based tests, and unit tests - Add rustfmt.toml configuration - Update documentation (API, ARCHITECTURE, DATA_STRUCTURES, README)
