feat: Add URL-specific crawler configurations for multi-URL crawling

Implement dynamic configuration selection based on URL patterns to optimize crawling for different content types. This feature enables users to apply different crawling strategies (PDF extraction, content filtering, JavaScript execution) based on URL matching patterns.

Key additions:
- Add url_matcher and match_mode parameters to CrawlerRunConfig
- Implement is_match() method supporting string patterns, functions, and mixed lists
- Add MatchMode enum for OR/AND logic when combining multiple matchers
- Update AsyncWebCrawler.arun_many() to accept List[CrawlerRunConfig]
- Add select_config() method to dispatchers for runtime config selection
- First matching config wins, with fallback to default

Pattern matching supports:
- Glob-style strings: *.pdf, */blog/*, *api*
- Lambda functions: lambda url: 'github.com' in url
- Mixed patterns with AND/OR logic for complex matching

This enables optimal per-URL configuration:
- PDFs: Use PDFContentScrapingStrategy without JavaScript
- Blogs: Apply content filtering to reduce noise
- APIs: Skip JavaScript, use JSON extraction
- Dynamic sites: Execute only necessary JavaScript

Breaking changes: None - fully backward compatible

+| **`url_matcher`**      | `UrlMatcher` (None)          | Pattern(s) to match URLs against. Can be: string (glob), function, or list of mixed types                                         |
+| **`match_mode`**       | `MatchMode` (MatchMode.OR)   | How to combine multiple matchers in a list: `MatchMode.OR` (any match) or `MatchMode.AND` (all must match)                       |
+
+The `url_matcher` parameter enables URL-specific configurations when used with `arun_many()`:
+
+```python
+from crawl4ai import CrawlerRunConfig, MatchMode
+from crawl4ai.processors.pdf import PDFContentScrapingStrategy
+from crawl4ai.extraction_strategy import JsonCssExtractionStrategy
+
+# Simple string pattern (glob-style)
+pdf_config = CrawlerRunConfig(
+    url_matcher="*.pdf",
+    scraping_strategy=PDFContentScrapingStrategy()
+)
+
+# Multiple patterns with OR logic (default)
+blog_config = CrawlerRunConfig(
+    url_matcher=["*/blog/*", "*/article/*", "*/news/*"],
+    match_mode=MatchMode.OR  # Any pattern matches
+)
+
+# Function matcher
+api_config = CrawlerRunConfig(
+    url_matcher=lambda url: 'api' in url or url.endswith('.json'),
+    extraction_strategy=JsonCssExtractionStrategy({"data": "body"})
+)
+
+# Mixed: String + Function with AND logic
+complex_config = CrawlerRunConfig(
+    url_matcher=[
+        lambda url: url.startswith('https://'),  # Must be HTTPS
+        "*.org/*",                               # Must be .org domain
+        lambda url: 'docs' in url                # Must contain 'docs'
+    ],
+    match_mode=MatchMode.AND  # ALL conditions must match
+)
+
+# Combined patterns and functions with AND logic
+secure_docs = CrawlerRunConfig(
+    url_matcher=["https://*", lambda url: '.doc' in url],
+    match_mode=MatchMode.AND  # Must be HTTPS AND contain .doc
+)
+```
+
+**UrlMatcher Types:**
+- **String patterns**: Glob-style patterns like `"*.pdf"`, `"*/api/*"`, `"https://*.example.com/*"`
+- **Functions**: `lambda url: bool` - Custom logic for complex matching
+- **Lists**: Mix strings and functions, combined with `MatchMode.OR` or `MatchMode.AND`
+
+When passing a list of configs to `arun_many()`, URLs are matched against each config's `url_matcher` in order. First match wins!
