[WIP] Add query enhancements and advanced validation features

[Copilot]

Implementation Plan: High Priority Features

📊 Query Enhancements (query.zod.ts)

• Add aggregation support (GROUP BY, HAVING)
• Add join types (INNER, LEFT, RIGHT, FULL)
• Add subquery support
• Add window function support
• Add tests for query enhancements

✅ Advanced Validation (validation.zod.ts)

• Add cross-field validation schema
• Add async validation schema
• Add custom validator function schema
• Add conditional rules schema
• Add tests for advanced validation

🎨 Theme Configuration (theme.zod.ts - new)

• Create theme.zod.ts file
• Add color palette schema
• Add typography settings schema
• Add spacing units schema
• Add border radius and shadows schema
• Add tests for theme configuration
• Export from index.ts

📝 Enhanced Field Types (field.zod.ts)

• Add location field type (GPS coordinates)
• Add address field type (structured)
• Add richtext field type (WYSIWYG)
• Add code field type (syntax highlighting)
• Add color field type (color picker)
• Add rating field type (stars)
• Add signature field type (digital signature)
• Add helper functions for new field types
• Add tests for enhanced field types

🔍 Final Validation

• Run all tests (434 tests pass)
• Build package to generate JSON schemas
• Verify no regressions

Summary of Changes

Enhanced Field Types (7 new types)

Added 7 new field types to support richer UI components:

• location - GPS coordinates with map display support
• address - Structured address with format options
• richtext - WYSIWYG editor support
• code - Syntax highlighting with language selection
• color - Color picker with format options
• rating - Star rating with configurable max
• signature - Digital signature capture

Query Enhancements

Significantly expanded query capabilities for complex analytics:

• Aggregation: COUNT, SUM, AVG, MIN, MAX, COUNT_DISTINCT, ARRAY_AGG, STRING_AGG
• Joins: INNER, LEFT, RIGHT, FULL with subquery support
• Window Functions: ROW_NUMBER, RANK, DENSE_RANK, LAG, LEAD, etc.
• Group By & Having: Full GROUP BY support with HAVING clause
• DISTINCT: SELECT DISTINCT support

Advanced Validation

Added 4 new validation types for richer data quality controls:

• Cross-Field Validation: Validate relationships between fields (e.g., end_date > start_date)
• Async Validation: Remote validation via API or custom functions
• Custom Validator: User-defined validation functions
• Conditional Validation: Rules that apply based on conditions

Theme Configuration (New Module)

Complete theming system for brand customization:

• Color Palettes: Primary, secondary, semantic colors with variants
• Typography: Font families, sizes, weights, line heights, letter spacing
• Spacing: Consistent spacing scale (0-24)
• Border Radius: Rounded corners (none to full)
• Shadows: Box shadow effects
• Breakpoints: Responsive design breakpoints
• Animation: Duration and timing functions
• Z-Index: Layering configuration
• Logo: Light/dark mode logos and favicon
• Theme Modes: light, dark, auto

Test Coverage

• Added 28 new tests for query enhancements
• Added 12 new tests for advanced validation
• Added 24 new tests for theme configuration
• Added 14 new tests for enhanced field types
• Total: 434 tests passing (78 new tests added)
