Consolidate workflows and tools from commands repository

Repository Restructure:
- Move all 83 agent .md files to agents/ subdirectory
- Add 15 workflow orchestrators from commands repo to workflows/
- Add 42 development tools from commands repo to tools/
- Update README for unified repository structure

The commands repository functionality is now fully integrated, providing
complete workflow orchestration and development tooling alongside agents.

Directory Structure:
- agents/    - 83 specialized AI agents
- workflows/ - 15 multi-agent orchestration commands
- tools/     - 42 focused development utilities

No breaking changes to agent functionality - all agents remain accessible
with same names and behavior. Adds workflow and tool commands for enhanced
multi-agent coordination capabilities.

+# Data Validation Pipeline
+
+Create a comprehensive data validation system for: $ARGUMENTS
+
+Implement validation including:
+
+1. **Schema Validation**:
+   - Pydantic models for structure
+   - JSON Schema generation
+   - Type checking and coercion
+   - Nested object validation
+   - Custom validators
+
+2. **Data Quality Checks**:
+   - Null/missing value handling
+   - Outlier detection
+   - Statistical validation
+   - Business rule enforcement
+   - Referential integrity
+
+3. **Data Profiling**:
+   - Automatic type inference
+   - Distribution analysis
+   - Cardinality checks
+   - Pattern detection
+   - Anomaly identification
+
+4. **Validation Rules**:
+   - Field-level constraints
+   - Cross-field validation
+   - Temporal consistency
+   - Format validation (email, phone, etc.)
+   - Custom business logic
+
+5. **Error Handling**:
+   - Detailed error messages
+   - Error categorization
+   - Partial validation support
+   - Error recovery strategies
+   - Validation reports
+
+6. **Performance**:
+   - Streaming validation
+   - Batch processing
+   - Parallel validation
+   - Caching strategies
+   - Incremental validation
+
+7. **Integration**:
+   - API endpoint validation
+   - Database constraints
+   - Message queue validation
+   - File upload validation
+   - Real-time validation
+
+Include data quality metrics, monitoring dashboards, and alerting. Make it extensible for custom validation rules.
