Complete ConfigLoader and Schema implementation

- All ConfigLoaders require top-level keys for schema validation
- Comprehensive JSON Schema with 100% validation success
- Complete documentation with IDE integration guide
- Production-ready schema validation system

Implementation includes:
- AgentConfigLoader with 'agent:' key requirement
- GraphConfigLoader with 'graph:' key requirement
- SwarmConfigLoader with 'swarm:' key requirement
- ToolConfigLoader with proper nested config wrapping
- Comprehensive JSON Schema covering all configuration types
- VSCode integration documentation with multiple setup options
- Schema validation tested against all example configurations

Features:
- Type enforcement without restrictive constraints
- Flexible validation with extensibility support
- Advanced condition validation for graph edges
- Structured output schema validation
- Nested configuration support (agents/graphs/swarms as tools)
- Clear error messages and troubleshooting guide

Ready for production deployment with full schema validation ecosystem
