fix: improve n8n_list_workflows pagination clarity and performance (Issue #54)

- Changed misleading 'total' field to 'returned' to clarify it's the count in current page
- Added 'hasMore' boolean flag for clear pagination indication
- Added '_note' guidance when more data is available
- Applied same improvements to n8n_list_executions for consistency

Performance improvements:
- Tool now returns only minimal metadata instead of full workflow structure
- Reduced response size by ~95% (from thousands to ~10 tokens per workflow)
- Eliminated token limit errors when listing workflows with many nodes
- Updated descriptions and documentation to clarify minimal response
