Fix field name clashing with namespaced virtual field names

- Prefix built-in trigger fields with __builtin_ namespace
- Prefix custom trigger fields with __trigger_{slug}_ namespace
- Completely eliminates field name conflicts between triggers
- Maintains backward compatibility with existing workflows
- Virtual fields transparently handle the namespacing

+# Migration Guide: v0.0.23 → v0.0.24
+
+## What's New
+
+Version 0.0.24 introduces **trigger builder helpers** that dramatically reduce boilerplate when creating custom triggers, plus fixes field name clashing between built-in and external trigger parameters.
+
+## Breaking Changes
+
+**None** - This is a fully backward-compatible release. All existing triggers continue to work exactly as before.
+
+## New Features
+
+### 1. Trigger Builder Helpers
+
+New helper functions eliminate 90% of boilerplate when creating custom triggers:
+
+```bash
+npm update @xtr-dev/payload-automation
+```
+
+```typescript
+// Import the new helpers
+import { 
+  createTrigger, 
+  webhookTrigger, 
+  cronTrigger 
+} from '@xtr-dev/payload-automation/helpers'
+```
+
+### 2. Fixed Field Name Clashing
+
+Built-in trigger parameters now use a JSON backing store to prevent conflicts with custom trigger fields.
+
+## Migration Steps
+
+### Step 1: Update Package
+
+```bash
+npm install @xtr-dev/payload-automation@latest
+# or
+pnpm update @xtr-dev/payload-automation
+```
+
+### Step 2: (Optional) Modernize Custom Triggers
+
+**Your existing triggers will continue to work**, but you can optionally migrate to the cleaner syntax:
+
+#### Before (Still Works)
+```typescript
+const customTrigger = {
+  slug: 'order-webhook',
+  inputs: [
+    {
+      name: 'webhookSecret',
+      type: 'text',
+      required: true,
+      virtual: true,
+      admin: {
+        condition: (_, siblingData) => siblingData?.type === 'order-webhook',
+        description: 'Secret for webhook validation'
+      },
+      hooks: {
+        afterRead: [({ siblingData }) => siblingData?.parameters?.webhookSecret],
+        beforeChange: [({ value, siblingData }) => {
+          if (!siblingData.parameters) siblingData.parameters = {}
+          siblingData.parameters.webhookSecret = value
+          return undefined
+        }]
+      }
+    }
+    // ... more boilerplate
+  ]
+}
+```
+
+#### After (Recommended)
+```typescript
+import { createTrigger } from '@xtr-dev/payload-automation/helpers'
+
+const orderWebhook = createTrigger('order-webhook').parameters({
+  webhookSecret: {
+    type: 'text',
+    required: true,
+    admin: {
+      description: 'Secret for webhook validation'
+    }
+  }
+  // Add more parameters easily
+})
+```
+
+### Step 3: (Optional) Use Preset Builders
+
+For common trigger patterns:
+
+```typescript
+import { webhookTrigger, cronTrigger } from '@xtr-dev/payload-automation/helpers'
+
+// Webhook trigger with built-in path, secret, headers parameters
+const paymentWebhook = webhookTrigger('payment-webhook')
+  .parameter('currency', {
+    type: 'select',
+    options: ['USD', 'EUR', 'GBP']
+  })
+  .build()
+
+// Cron trigger with built-in expression, timezone parameters  
+const dailyReport = cronTrigger('daily-report')
+  .parameter('format', {
+    type: 'select',
+    options: ['pdf', 'csv']
+  })
+  .build()
+```
+
+## Quick Migration Examples
+
+### Simple Trigger Migration
+
+```typescript
+// OLD WAY (still works)
+{
+  slug: 'user-signup',
+  inputs: [/* 20+ lines of boilerplate per field */]
+}
+
+// NEW WAY (recommended)
+import { createTrigger } from '@xtr-dev/payload-automation/helpers'
+
+const userSignup = createTrigger('user-signup').parameters({
+  source: {
+    type: 'select',
+    options: ['web', 'mobile', 'api'],
+    required: true
+  },
+  userType: {
+    type: 'select', 
+    options: ['regular', 'premium'],
+    defaultValue: 'regular'
+  }
+})
+```
+
+### Webhook Trigger Migration
+
+```typescript
+// OLD WAY
+{
+  slug: 'payment-webhook',
+  inputs: [/* Manual webhookPath field + lots of boilerplate */]
+}
+
+// NEW WAY  
+import { webhookTrigger } from '@xtr-dev/payload-automation/helpers'
+
+const paymentWebhook = webhookTrigger('payment-webhook')
+  .parameter('minimumAmount', { 
+    type: 'number', 
+    min: 0 
+  })
+  .build()
+```
+
+## Benefits of Migration
+
+- **90% less code** - Eliminate virtual field boilerplate
+- **No field name conflicts** - Built-in parameters isolated
+- **Better TypeScript support** - Full type inference
+- **Preset patterns** - Common trigger types ready-to-use
+- **Composable API** - Easy to extend and customize
+
+## Compatibility
+
+- ✅ **Existing triggers** continue to work unchanged
+- ✅ **Mix old and new** trigger styles in same config
+- ✅ **No database changes** required
+- ✅ **PayloadCMS field compatibility** maintained
+
+## Need Help?
+

+- [Read documentation](./examples/README-trigger-builders.md)
+- [Report issues](https://github.com/xtr-dev/payload-automation/issues)
+
+---
+
+**TL;DR**: Update the package, optionally migrate custom triggers to use the new helpers for cleaner code. All existing triggers continue to work without changes.
