Refactor tests and update pre-commit configuration

- Updated test cases in various files to use range-based loops for better readability and performance. - Modified the `justfile` to include `tidy` in the `all` target. - Enhanced `pre-commit-config.yaml` to ensure proper linting and formatting for Go files. - Added comprehensive tests for rate limiting and WebSocket functionalities in `utils` and `wsstream`. - Improved error handling and edge case coverage in existing tests.
