feat: implement AI-optimized MCP tools with 95% size reduction
- Add get_node_essentials tool for 10-20 essential properties only - Add search_node_properties for targeted property search - Add get_node_for_task with 14 pre-configured templates - Add validate_node_config for comprehensive validation - Add get_property_dependencies for visibility analysis - Implement PropertyFilter service with curated essentials - Implement ExampleGenerator with working examples - Implement TaskTemplates for common workflows - Implement ConfigValidator with security checks - Implement PropertyDependencies for dependency analysis - Enhance property descriptions to 100% coverage - Add version information to essentials response - Update documentation with new tools Response sizes reduced from 100KB+ to <5KB for better AI agent usability. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
