TypeScript interface-like schema validation system that's easier to use than Zod

# Documentation Update Summary

## Overview

Successfully updated all documentation to include the comprehensive set of 20 conditional validation operators that were implemented in the Fortify Schema system.

## ✅ **COMPLETED: Documentation Updates**

### 📚 **Updated Documentation Files**

1. **`docs/VALIDATION-OPERATORS.md`** - Complete operator reference
2. **`README.md`** - Main documentation with operator overview
3. **Test file fixes** - Fixed `src/core/private/gl.ts` test data

### 🔧 **Test Verification**

**Test Command:** `bun src/core/private/gl.ts`
**Result:** ✅ **ALL OPERATORS WORKING CORRECTLY**

```
🚀 TESTING MODULAR CONDITIONAL OPERATORS SYSTEM
===============================================

1. Testing ALL operators with valid data:
Valid result success: true
✅ SUCCESS: All operators working correctly!
✅ Modular system successfully handles ALL operators!
```

## 📊 **Complete Operator Documentation**

### **Comparison Operators (6)**
- `=` - Equals
- `!=` - Not equals  
- `>` - Greater than
- `<` - Less than
- `>=` - Greater than or equal
- `<=` - Less than or equal

### **Pattern Operators (2)**
- `~` - Regex match
- `!~` - Negative regex match

### **Existence Operators (2)**
- `.exists` - Field exists (not null/undefined)
- `.!exists` - Field does not exist

### **State Operators (4)**
- `.empty` - Field is empty (string/array/object)
- `.!empty` - Field is not empty
- `.null` - Field is exactly null
- `.!null` - Field is not null

### **Array Operators (2)**
- `.in()` - Value in array
- `.!in()` - Value not in array

### **String Operators (4)**
- `.startsWith()` - String starts with value
- `.endsWith()` - String ends with value
- `.contains()` - String contains value
- `.!contains()` - String does not contain value

**Total: 20 Operators** - All documented and tested ✅

## 📖 **Documentation Structure**

### **VALIDATION-OPERATORS.md**
- ✅ Complete operator reference tables
- ✅ Syntax examples for all 3 formats
- ✅ IDE support analysis
- ✅ Operator precedence documentation
- ✅ Best practices and migration guide
- ✅ Real-world examples

### **README.md**
- ✅ Updated condition operators section
- ✅ Comprehensive operator categorization
- ✅ Examples for each operator type
- ✅ Integration with existing documentation

## 🎯 **Key Documentation Features**

### **Operator Categories**
Organized operators into logical groups for better understanding:
- Comparison (basic equality/inequality)
- Pattern (regex operations)
- Existence (null/undefined checks)
- State (empty/full checks)
- Array (inclusion operations)
- String (text operations)

### **IDE Support Indicators**
Clear indicators for each operator:
- ✅ **Full TypeScript inference** (19 operators)
- ⚠️ **Runtime only, no IDE errors** (1 operator: `!=`)

### **Syntax Examples**
Comprehensive examples showing:
- Revolutionary `*?` syntax (recommended)
- Parentheses syntax (alternative)
- When.field() API (programmatic)

### **Operator Precedence**
Documented the complete parsing order (highest to lowest):
1. Existence operators (`.!exists`, `.exists`)
2. State operators (`.!empty`, `.empty`, `.!null`, `.null`)
3. Array operators (`.!in()`, `.in()`)
4. Pattern operators (`!~`, `~`)
5. String operators (`.!contains()`, `.contains()`, `.endsWith()`, `.startsWith()`)
6. Comparison operators (`!=`, `>=`, `<=`, `>`, `<`, `=`)

## 🚀 **Real-World Examples**

### **File Processing System**
```typescript
const fileSchema = Interface({
  filename: "string",
  size: "number",
  compression: "when filename.endsWith(.zip) *? =high : =none",
  processingQueue: "when size>1000000 *? =background : =immediate",
  needsBackup: "when filename.startsWith(important_) *? =true : =false",
  extractMetadata: "when filename.contains(.pdf) *? =true : =false",
});
```

### **User Management System**
```typescript
const userSchema = Interface({
  role: "admin|user|guest",
  email: "email",
  permissions: "when role=admin *? string[] : string[]?",
  adminAccess: "when email~^admin *? =true : =false",
  billingAddress: "when paymentMethod.exists *? string : string?",
  restrictions: "when role.!in(guest) *? string[] : string[]?",
});
```
