tegwick 796c04709a feat: implement JavaScript-first TestDriveJSUI library (v1.0.0)

Completed Phase 1 refactoring to JavaScript-first architecture:

Core Library Implementation:
- Created js/testdrive-jsui.js main library class
- Integrated all existing components (SectionManager, DOMRenderer, DocumentControls)
- Added marked.js integration for markdown rendering
- Implemented event-driven API (on/off/emit)
- Support for edit/view modes and themes
- LocalStorage save/load functionality
- Download as markdown file
- Keyboard shortcuts (Ctrl+S, Escape)
- Auto-save capability (optional)

Examples:
- examples/full-editor.html - Complete demo with all features
- Updated examples/README.md with full documentation

Documentation:
- Updated README.md with JavaScript-first architecture section
- Added complete API reference (constructor, methods, events)
- Updated CLAUDE.md with library quick start and API
- Emphasized JavaScript-first design principles

Architecture:
- JavaScript provides ALL functionality
- Language adapters are optional integration helpers
- Works standalone in browser (no backend required)
- Clean separation: JS (functionality) vs Adapters (integration)

This completes the architectural shift documented in ARCHITECTURE.md
and JS_FIRST_REFACTORING.md Phase 1.

TestDrive-JSUI Examples

This directory contains examples demonstrating TestDrive-JSUI as a standalone JavaScript library.

📁 Examples

`standalone.html` - Proof of Concept

Purpose: Minimal proof that TestDrive-JSUI can work as a pure JavaScript library.

Features:

✅ Runs directly in browser (no server needed)
✅ Markdown rendering using marked.js
✅ Save/load to browser localStorage
✅ Download markdown files
✅ Zero dependencies on Python/Ruby/Java

How to Use:

# Option 1: Open directly in browser
open examples/standalone.html

# Option 2: From file system (works!)
# Just double-click the file

# Option 3: Serve with any static server
python3 -m http.server 8000
# Then visit: http://localhost:8000/examples/standalone.html

What It Demonstrates:

JavaScript can handle all rendering
No backend is required for core functionality
Language adapters (Python/Ruby/Java) are truly optional

`full-editor.html` - Complete Library Demo

Purpose: Demonstrates the full TestDriveJSUI library with all features.

Features:

✅ Full Library Integration: Uses complete TestDriveJSUI class
✅ Section-Based Editing: Click sections to edit them independently
✅ Interactive Controls: Floating control panel with document operations
✅ Event System: Listen to save, content-changed, and other events
✅ Multiple Modes: Switch between edit and view modes
✅ Auto-save: Optional automatic saving (currently disabled)
✅ Keyboard Shortcuts: Ctrl+S to save, Escape to close editor
✅ Status Bar: Real-time document statistics
✅ Image Editing: Advanced image editing with drag & drop

How to Use:

# Serve with any static server (required for proper module loading)
python3 -m http.server 8000
# Then visit: http://localhost:8000/examples/full-editor.html

What It Demonstrates:

Complete TestDriveJSUI API usage
Integration of all components (SectionManager, DOMRenderer, DocumentControls)
Event-driven architecture
Mode switching (edit/view)
Document operations (save, load, download, reset)
Real-time status updates

API Example from Demo:

// Initialize editor
const editor = new TestDriveJSUI({
    container: '#editor-container',
    markdown: '# Hello World',
    mode: 'edit',
    theme: 'github',
    autosave: false,
    shortcuts: true
});

// Listen to events
editor.on('save', (data) => {
    console.log('Saved:', data.markdown);
});

// Get/set content
const markdown = editor.getMarkdown();
editor.setMarkdown('# Updated content');

// Get status
const status = editor.getStatus();
console.log('Sections:', status.totalSections);

🎯 Architecture Validation

These examples validate the JavaScript-first architecture:

✅ Implemented Features

Markdown parsing (marked.js)
HTML rendering
UI display and styling
Content management
Save/load (localStorage)
File download
Interactive editing UI ✅
Section-based editing ✅
Control panels (edit, debug, status) ✅
Keyboard shortcuts ✅
Themes ✅
Event system ✅

🚧 Future Enhancements

Plugin system
Additional themes
Collaborative editing
Cloud storage adapters
Mobile-optimized UI

🔧 What Backend Adapters Provide (Optional)

Asset serving at scale
Server-side storage
User authentication
Multi-user collaboration
Testing infrastructure

🚀 Getting Started

1. Try the Proof of Concept

# Open standalone.html in any browser
open examples/standalone.html

# Test basic functionality:
# - Markdown rendering
# - Save/load/download buttons

2. Explore the Full Editor

# Serve the examples directory
cd examples
python3 -m http.server 8000

# Open in browser:
# http://localhost:8000/full-editor.html

# Test advanced features:
# - Click sections to edit
# - Use toolbar buttons
# - Try keyboard shortcuts (Ctrl+S, Escape)
# - Switch between edit/view modes

3. Integrate Into Your Project

<!DOCTYPE html>
<html>
<head>
    <script src="https://cdn.jsdelivr.net/npm/marked/marked.min.js"></script>
    <script src="path/to/testdrive-jsui.js"></script>
</head>
<body>
    <div id="editor"></div>
    <script>
        const editor = new TestDriveJSUI({
            container: '#editor',
            markdown: '# Start writing...',
            mode: 'edit'
        });
    </script>
</body>
</html>

📝 Notes

Performance: Loading from CDN (marked.js) means internet connection required. For fully offline use, download marked.js locally.

Browser Support: Works in all modern browsers (Chrome, Firefox, Safari, Edge). Requires ES6 support.

File Size: The standalone example loads individual JS files. Production version would use bundled testdrive-jsui.min.js (~50KB).
