- Introduced `NyxError` and `NyxResult` for unified error handling across modules. - Refactored `scan.rs`, `index.rs`, and `walk.rs` with improved error management and consistent formatting. - Replaced existing error handling in `database.rs` with `NyxResult`. - Improved database maintenance by integrating `vacuum` and `clear` methods into workflows. - Added `dashmap` for efficient parallel diagnostics result aggregation in `scan_with_index_parallel`. - Enhanced readability and formatting of console outputs in multiple modules.
