feat: Refactor tool imports and improve progress logging

- Changed imports in multiple tool files to use type imports for `InferUITool` and standard imports for `createTool` for consistency and clarity.
- Updated progress logging in various tools to use `writer?.custom` with `type: 'data-tool-progress'` instead of `writer?.write` with `type: 'progress'` to standardize the logging approach.
- Cleaned up unnecessary whitespace in several files for better readability.
- Enhanced error handling messages to use nullish coalescing operator (`??`) for default values in Python analysis and complexity functions.
- Improved the test generator tool by ensuring consistent formatting and handling of edge cases in test case generation.
