feat(demo): add DeesDemoWrapper component for enhanced demo element handling

+## Demo Tools
+
+### DeesDemoWrapper Component
+A utility component for wrapping demo elements with post-render functionality.
+
+**Usage:**
+```typescript
+import { DeesDemoWrapper } from '@design.estate/dees-wcctools/demoTools';
+
+// In your demo function:
+demo: () => html`
+  <dees-demowrapper .runAfterRender=${(element) => {
+    // Do something with the rendered element
+    element.setAttribute('data-demo', 'true');
+    console.log('Element rendered:', element);
+  }}>
+    <my-custom-element></my-custom-element>
+  </dees-demowrapper>
+`
+```
+
+**Features:**
+- Wraps demo elements without affecting layout (uses `display: contents`)
+- Provides access to the rendered element instance after mounting
+- Supports async operations in runAfterRender callback
+- Automatically handles timing to ensure element is fully rendered

 ## Implementation Plan
 
-### 1. Add proper synchronization
+### 1. Add proper synchronization ✅
 - Add a delay or await render completion before element detection
 - Use MutationObserver or lit's updateComplete promises
 
-### 2. Improve element search algorithm
+### 2. Improve element search algorithm ✅
 - Search recursively through all descendants, not just direct children
 - Handle shadow DOM boundaries properly
 - Support elements wrapped in containers
 
-### 3. Add retry mechanism

 - If element not found, retry after a delay
 - Add maximum retry attempts to prevent infinite loops
 - Clear error state when element is eventually found

+## Created DeesDemoWrapper Component
+- Location: ts_demotools/demotools.ts
+- Allows wrapping demo elements with post-render functionality
+- Provides runAfterRender callback that receives the rendered element
+- Uses display: contents to not affect layout
+- Handles timing automatically with 50ms delay after firstUpdated
+- Supports both sync and async callbacks
+- Exports available at @design.estate/dees-wcctools/demoTools
