feat: enhance tool descriptions for better Smithery.ai marketplace visibility

🔧 Tool Description Improvements:
- list_workflows: Detailed explanation of workflow overview capabilities
- create_workflow: Comprehensive description of programmatic workflow creation
- get_workflow: Clear explanation of workflow inspection functionality
- execute_workflow: Detailed manual execution trigger description
- update_workflow: Explanation of partial update capabilities
- activate_workflow: Clear description of workflow enablement process
- deactivate_workflow: Detailed explanation of workflow suspension
- delete_workflow: Warning about permanent deletion with use cases

📈 Benefits:
- Better tool discovery in Smithery.ai marketplace
- Clearer user understanding of each tool's purpose
- More informative tool playground experience
- Enhanced documentation for AI assistant integration

These enhanced descriptions will be reflected on the Smithery.ai server page
at https://smithery.ai/server/@makafeli/n8n-workflow-builder after redeployment.
