Pull Request Overview
This PR adds a comprehensive "revert-useless-changes" tool designed with functional programming principles to automatically detect and revert files with only cosmetic changes (whitespace or comments) in Git repositories.
- Implements a rule-based analysis system with two built-in rules: whitespace-only changes and comment-only changes using AST comparison
- Provides both CLI and programmatic API with TypeScript support and comprehensive error handling
- Features extensible architecture allowing easy addition of new analysis rules and output formats

Using 'as any' defeats TypeScript's type safety. Consider using a specific ECMAScript version number like 2022 or checking the @typescript-eslint/parser documentation for valid ecmaVersion values.

Direct console.warn usage bypasses the centralized logging system. Consider using a logger parameter or the reporter module's logWarning function for consistent error handling.

This pattern matching implementation is incorrect. Removing all wildcards and using string.includes() will produce false matches. For example, pattern '*.txt' would match 'file.txt.backup' incorrectly.

The matchesPattern function is incomplete - it only handles '**/*' and simple extension patterns but returns false for all other cases. This could cause rules to not apply to files they should match.
