feat: Enhance stealth compatibility with new and legacy APIs, add configuration support

Fixes #1273

- Replace deprecated stealth_async import with Stealth class
- Add stealth flag to BrowserConfig (default: true)
- Update async_crawler_strategy to use Stealth().apply_stealth_async()
- Remove obsolete StealthConfig from browser_manager
- Maintain backward compatibility with existing stealth functionality

This fixes compatibility issues with playwright-stealth v2.0.0+ where the API changed from stealth_async function to Stealth class.

test: Add comprehensive tests for playwright-stealth v2.0.0+ compatibility

- Test Stealth class import and instantiation
- Test apply_stealth_async method availability
- Test BrowserConfig stealth flag functionality
- Test stealth flag serialization
- Verify backward compatibility with existing stealth functionality

-# 🛠️ Crawl4AI v0.7.1: Minor Cleanup Update
-
-*July 17, 2025 • 2 min read*
-
----
-
-A small maintenance release that removes unused code and improves documentation.
-
-## 🎯 What's Changed
-
-- **Removed unused StealthConfig** from `crawl4ai/browser_manager.py`
-- **Updated documentation** with better examples and parameter explanations
-- **Fixed virtual scroll configuration** examples in docs
-
-## 🧹 Code Cleanup
-
-Removed unused `StealthConfig` import and configuration that wasn't being used anywhere in the codebase. The project uses its own custom stealth implementation through JavaScript injection instead.
-
-```python
-# Removed unused code:
-from playwright_stealth import StealthConfig
-stealth_config = StealthConfig(...)  # This was never used
-```
-
-## 📖 Documentation Updates
-
-- Fixed adaptive crawling parameter examples
-- Updated session management documentation
-- Corrected virtual scroll configuration examples
-
-## 🚀 Installation
-
-```bash
-pip install crawl4ai==0.7.1
-```
-
-No breaking changes - upgrade directly from v0.7.0.
