fix: standardize file parameter naming across all tools

- Change `relevant_files` to `files` in debug_issue tool
- Change `reference_files` to `files` in think_deeper tool
- Now all tools consistently use `files` parameter name
- Fix cross-platform test for Windows path separators
- Update README to reflect consistent parameter naming

This improves API consistency and reduces confusion when using different tools.
