feat: add operation and resource validation with intelligent suggestions
- Added OperationSimilarityService for validating operations with "Did you mean...?" suggestions - Added ResourceSimilarityService for validating resources with plural/singular detection - Implements Levenshtein distance algorithm for typo detection - Pattern matching for common operation/resource mistakes - 5-minute cache with automatic cleanup to prevent memory leaks - Confidence scoring (30% minimum threshold) for suggestion quality - Resource-aware operation filtering for contextual suggestions - Safe JSON parsing with ValidationServiceError for proper error handling - Type guards for safe property access - Performance optimizations with early termination - Comprehensive test coverage (37 new tests) - Integration tested with n8n-mcp-tester agent Example use cases: - "listFiles" → suggests "search" for Google Drive - "files" → suggests singular "file" - "flie" → suggests "file" (typo correction) - "downlod" → suggests "download" 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
