refactor(models): rename final_url to redirected_url for consistency

Renames the final_url field to redirected_url across all components to maintain
consistent terminology throughout the codebase. This change affects:
- AsyncCrawlResponse model
- AsyncPlaywrightCrawlerStrategy
- Documentation and examples

No functional changes, purely naming consistency improvement.

-# Crawl4AI 0.4.3b1 is Here: Faster, Smarter, and Ready for Real-World Crawling!
+# Crawl4AI 0.4.3: Major Performance Boost & LLM Integration
 
-Hey, Crawl4AI enthusiasts! We're thrilled to announce the release of **Crawl4AI 0.4.3b1**, packed with powerful new features and enhancements that take web crawling to a whole new level of efficiency and intelligence. This release is all about giving you more control, better performance, and deeper insights into your crawled data.
+We're excited to announce Crawl4AI 0.4.3, focusing on three key areas: Speed & Efficiency, LLM Integration, and Core Platform Improvements. This release significantly improves crawling performance while adding powerful new LLM-powered features.
 
-Let's dive into what's new!
+## ⚡ Speed & Efficiency Improvements
 
-## 🚀 Major Feature Highlights
+### 1. Memory-Adaptive Dispatcher System
-
+The new dispatcher system provides intelligent resource management and real-time monitoring:
-### 1. LLM-Powered Schema Generation: Zero to Structured Data in Seconds!
-
-Tired of manually crafting CSS or XPath selectors? We've got you covered! Crawl4AI now features a revolutionary **schema generator** that uses the power of Large Language Models (LLMs) to automatically create extraction schemas for you.
-
-**How it Works:**
-
-1. **Provide HTML**: Feed in a sample HTML snippet that contains the type of data you want to extract (e.g., product listings, article sections).
-2. **Describe Your Needs (Optional)**: You can provide a natural language query like "extract all product names and prices" to guide the schema creation.
-3. **Choose Your LLM**: Use either **OpenAI** (GPT-4o recommended) for top-tier accuracy or **Ollama** for a local, open-source option.
-4. **Get Your Schema**: The tool outputs a ready-to-use JSON schema that works seamlessly with `JsonCssExtractionStrategy` or `JsonXPathExtractionStrategy`.
-
-**Why You'll Love It:**
-
--   **No More Tedious Selector Writing**: Let the LLM analyze the HTML and create the selectors for you!
--   **One-Time Cost**: Schema generation uses LLM, but once you have your schema, subsequent extractions are fast and LLM-free.
--   **Handles Complex Structures**: The LLM can understand nested elements, lists, and variations in layout—far beyond what simple CSS selectors can achieve.
--   **Learn by Example**: The generated schemas are a fantastic way to learn best practices for writing your own schemas.
-
-**Example:**
 
 ```python
-from crawl4ai.extraction_strategy import JsonCssExtractionStrategy
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, DisplayMode
-
+from crawl4ai.async_dispatcher import MemoryAdaptiveDispatcher, CrawlerMonitor
-# Sample HTML snippet (imagine this is part of a product listing page)
-html = """
-<div class="product">
-    <h2 class="name">Awesome Gadget</h2>
-    <span class="price">$99.99</span>
-</div>
-"""
-
-# Generate schema using OpenAI
-schema = JsonCssExtractionStrategy.generate_schema(
-    html,
-    llm_provider="openai/gpt-4o",
-    api_token="YOUR_API_TOKEN"
-)
-
-# Or use Ollama for a local, open-source option
-# schema = JsonCssExtractionStrategy.generate_schema(
-#     html,
-#     llm_provider="ollama/llama3"
-# )
-
-print(json.dumps(schema, indent=2))
-```
-
-**Output (Schema):**
-
-```json
-{
-  "name": null,
-  "baseSelector": "div.product",
-  "fields": [
-    {
-      "name": "name",
-      "selector": "h2.name",
-      "type": "text"
-    },
-    {
-      "name": "price",
-      "selector": "span.price",
-      "type": "text"
-    }
-  ]
-}
-```
-
-You can now **save** this schema and use it for all your extractions on pages with the same structure. No more LLM costs, just **fast, reliable** data extraction!
-
-### 2. Robots.txt Compliance: Crawl Responsibly
-
-Crawl4AI now respects website rules! With the new `check_robots_txt=True` option in `CrawlerRunConfig`, the crawler automatically fetches, parses, and obeys each site's `robots.txt` file.
-
-**Key Features**:
-
--   **Efficient Caching**: Stores parsed `robots.txt` files locally for 7 days to avoid re-fetching.
--   **Automatic Integration**: Works seamlessly with both `arun()` and `arun_many()`.
--   **Clear Status Codes**: Returns a 403 status code if a URL is disallowed.
--   **Customizable**: Adjust the cache directory and TTL if needed.
-
-**Example**:
-
-```python
-from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, CacheMode
 
 async def main():
-    config = CrawlerRunConfig(
+    urls = ["https://example1.com", "https://example2.com"] * 50
-        cache_mode=CacheMode.ENABLED,
+    
-        check_robots_txt=True
+    # Configure memory-aware dispatch
-    )
+    dispatcher = MemoryAdaptiveDispatcher(
-
+        memory_threshold_percent=80.0,  # Auto-throttle at 80% memory
-    async with AsyncWebCrawler() as crawler:
+        check_interval=0.5,             # Check every 0.5 seconds
-        result = await crawler.arun("https://example.com/private-page", config=config)
+        max_session_permit=20,          # Max concurrent sessions
-        if result.status_code == 403:
+        monitor=CrawlerMonitor(         # Real-time monitoring
-            print("Access denied by robots.txt")
+            display_mode=DisplayMode.DETAILED
-
+        )
-if __name__ == "__main__":
+    )
-    asyncio.run(main())
+    
-```
+    async with AsyncWebCrawler() as crawler:
-
+        results = await dispatcher.run_urls(
-### 3. Proxy Support in `CrawlerRunConfig`
+            urls=urls,
-
+            crawler=crawler,
-Need more control over your proxy settings? Now you can configure proxies directly within `CrawlerRunConfig` for each crawl:
+            config=CrawlerRunConfig()
-
-```python
-from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
-
-async def main():
-    config = CrawlerRunConfig(
-        proxy_config={
-            "server": "http://your-proxy.com:8080",
-            "username": "your_username",  # Optional
-            "password": "your_password"  # Optional
-        }
-    )
-
-    async with AsyncWebCrawler() as crawler:
-        result = await crawler.arun("https://example.com", config=config)
-```
-
-This allows for dynamic proxy assignment per URL or even per request.
-
-### 4. LLM-Powered Markdown Filtering (Beta)
-
-We're introducing an experimental **`LLMContentFilter`**! This filter, when used with the `DefaultMarkdownGenerator`, can produce highly focused markdown output by using an LLM to analyze content relevance.
-
-**How it Works:**
-
-1. You provide an **instruction** (e.g., "extract only the key technical details").
-2. The LLM analyzes each section of the page based on your instruction.
-3. Only the most relevant content is included in the final `fit_markdown`.
-
-**Example**:
-
-```python
-from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
-from crawl4ai.content_filter_strategy import LLMContentFilter
-from crawl4ai.markdown_generation_strategy import DefaultMarkdownGenerator
-
-async def main():
-    llm_filter = LLMContentFilter(
-        provider="openai/gpt-4o",
-        api_token="YOUR_API_TOKEN",  # Or use "ollama/llama3" with no token
-        instruction="Extract the core educational content about Python classes."
-    )
-
-    config = CrawlerRunConfig(
-        markdown_generator=DefaultMarkdownGenerator(content_filter=llm_filter)
-    )
-
-    async with AsyncWebCrawler() as crawler:
-        result = await crawler.arun(
-            "https://docs.python.org/3/tutorial/classes.html",
-            config=config
         )
-        print(result.markdown_v2.fit_markdown)
-
-if __name__ == "__main__":
-    asyncio.run(main())
 ```
 
-**Note**: This is a beta feature. We're actively working on improving its accuracy and performance.
+### 2. Streaming Support
-
+Process crawled URLs in real-time instead of waiting for all results:
-### 5. Streamlined `arun_many()` with Dispatchers
-
-We've simplified concurrent crawling! `arun_many()` now intelligently handles multiple URLs, either returning a **list** of results or an **async generator** for streaming.
-
-**Basic Usage (Batch)**:
 
 ```python
-results = await crawler.arun_many(
+config = CrawlerRunConfig(stream=True)
-    urls=["https://site1.com", "https://site2.com"],
-    config=CrawlerRunConfig()
-)
 
-for res in results:
+async with AsyncWebCrawler() as crawler:
-    print(res.url, "crawled successfully:", res.success)
+    async for result in await crawler.arun_many(urls, config=config):
+        print(f"Got result for {result.url}")
+        # Process each result immediately
 ```
 
-**Streaming Mode**:
+### 3. LXML-Based Scraping
+New LXML scraping strategy offering up to 20x faster parsing:
 
 ```python
-async for result in await crawler.arun_many(
-    urls=["https://site1.com", "https://site2.com"],
-    config=CrawlerRunConfig(stream=True)
-):
-    print("Just finished:", result.url)
-    # Process each result immediately
-```
-
-**Advanced:** You can now customize how `arun_many` handles concurrency by passing a **dispatcher**. See [Advanced Multi-URL Crawling](../advanced/multi-url-crawling.md) for details.
-
-### 6. Enhanced Browser Context Management
-
-We've improved how Crawl4AI manages browser contexts for better resource utilization and session handling.
-
--   **`shared_data` in `CrawlerRunConfig`**: Pass data between hooks using the `shared_data` dictionary.
--   **Context Reuse**: The crawler now intelligently reuses browser contexts based on configuration, reducing overhead.
-
-### 7. Faster Scraping with `LXMLWebScrapingStrategy`
-
-Introducing a new, optional **`LXMLWebScrapingStrategy`** that can be **10-20x faster** than the default BeautifulSoup approach for large, complex pages.
-
-**How to Use**:
-
-```python
-from crawl4ai import LXMLWebScrapingStrategy
-
 config = CrawlerRunConfig(
-    scraping_strategy=LXMLWebScrapingStrategy()  # Add this line
+    scraping_strategy=LXMLWebScrapingStrategy(),
+    cache_mode=CacheMode.ENABLED
 )
 ```
 
-**When to Use**:
+## 🤖 LLM Integration
-- If profiling shows a bottleneck in `WebScrapingStrategy`.
-- For very large HTML documents where parsing speed matters.
 
-**Caveats**:
+### 1. LLM-Powered Markdown Generation
-- It might not handle malformed HTML as gracefully as BeautifulSoup.
+Smart content filtering and organization using LLMs:
-- We're still gathering data, so report any issues!
 
----
+```python
+config = CrawlerRunConfig(
+    markdown_generator=DefaultMarkdownGenerator(
+        content_filter=LLMContentFilter(
+            provider="openai/gpt-4o",
+            instruction="Extract technical documentation and code examples"
+        )
+    )
+)
+```
 
-## Try the Feature Demo Script!
+### 2. Automatic Schema Generation
+Generate extraction schemas instantly using LLMs instead of manual CSS/XPath writing:
 
-We've prepared a Python script demonstrating these new features. You can find it at:
+```python
+schema = JsonCssExtractionStrategy.generate_schema(
+    html_content,
+    schema_type="CSS",
+    query="Extract product name, price, and description"
+)
+```
 
-[**`features_demo.py`**](https://github.com/unclecode/crawl4ai/blob/main/docs/examples/0_4_3b1_feature_demo.py)
+## 🔧 Core Improvements
 
-**To run the demo:**
+### 1. Proxy Support & Rotation
+Integrated proxy support with automatic rotation and verification:
 
-1. Make sure you have Crawl4AI installed (`pip install crawl4ai`).
+```python
-2. Copy the `features_demo.py` script to your local environment.
+config = CrawlerRunConfig(
-3. Set your OpenAI API key as an environment variable (if using OpenAI models):
+    proxy_config={
-    ```bash
+        "server": "http://proxy:8080",
-    export OPENAI_API_KEY="your_api_key"
+        "username": "user",
-    ```
+        "password": "pass"
-4. Run the script:
+    }
-    ```bash
+)
-    python features_demo.py
+```
-    ```
 
-The script will execute various crawl scenarios, showcasing the new features and printing results to your console.
+### 2. Robots.txt Compliance
+Built-in robots.txt support with SQLite caching:
 
-## Conclusion
+```python
+config = CrawlerRunConfig(check_robots_txt=True)
+result = await crawler.arun(url, config=config)
+if result.status_code == 403:
+    print("Access blocked by robots.txt")
+```
 
-Crawl4AI version 0.4.3b1 is a major step forward in flexibility, performance, and ease of use. With automatic schema generation, robots.txt handling, advanced content filtering, and streamlined multi-URL crawling, you can build powerful, efficient, and responsible web scrapers.
+### 3. URL Redirection Tracking
+Track final URLs after redirects:
 
-We encourage you to try out these new capabilities, explore the updated documentation, and share your feedback! Your input is invaluable as we continue to improve Crawl4AI.
+```python
+result = await crawler.arun(url)
+print(f"Initial URL: {url}")
+print(f"Final URL: {result.redirected_url}")
+```
