- Add normalize_to_final_build() to map tune configs to final builds (323/233/332) - Add normalized_config field to BestCarRecord - Change CarCounts.by_rid key from String to (String, String) for per-config tracking - Change CarCounts.guid_to_rid to HashMap<String, HashSet<(String, String)>> - Extract owned tune configs from my_cars.json (engineMajor/weightMajor/chassisMajor) - Add improve command: owned cars not yet at final build, sorted by track count - Strip version prefixes (v2c_/v1c_) from config keys at parse time - Update dedup check in update_best_car to consider normalized_config - Add atomic_write helper for safe CSV output - Delete completed plans/code-review-v2.md - Apply rustfmt formatting across codebase
