feat(v2.7.0): add n8n_update_partial_workflow with transactional updates
BREAKING CHANGES: - Renamed n8n_update_workflow to n8n_update_full_workflow for clarity NEW FEATURES: - Added n8n_update_partial_workflow tool for diff-based workflow editing - Implemented WorkflowDiffEngine with 13 operation types - Added transactional updates with two-pass processing - Maximum 5 operations per request for reliability - Operations can be in any order - engine handles dependencies - Added validateOnly mode for testing changes before applying - 80-90% token savings by only sending changes IMPROVEMENTS: - Enhanced tool description with comprehensive parameter documentation - Added clear examples for simple and complex use cases - Improved error messages and validation - Added extensive test coverage for all operations DOCUMENTATION: - Added workflow-diff-examples.md with usage patterns - Added transactional-updates-example.md showing before/after - Updated README.md with v2.7.0 features - Updated CLAUDE.md with latest changes 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
