feat(crawler): add network request and console message capturing

Implement comprehensive network request and console message capturing functionality:
- Add capture_network_requests and capture_console_messages config parameters
- Add network_requests and console_messages fields to models
- Implement Playwright event listeners to capture requests, responses, and console output
- Create detailed documentation and examples
- Add comprehensive tests

This feature enables deep visibility into web page activity for debugging,
security analysis, performance profiling, and API discovery in web applications.

+The file /docs/md_v2/api/parameters.md should be updated to include the new network and console capturing parameters. 
+
+Here's what needs to be updated:
+
+1. Change section title from:
+```
+### G) **Debug & Logging**
+```
+to:
+```
+### G) **Debug, Logging & Capturing**
+```
+
+2. Add new parameters to the table:
+```
+| **`capture_network_requests`** | `bool` (False) | Captures all network requests, responses, and failures during the crawl. Available in `result.network_requests`. |
+| **`capture_console_messages`** | `bool` (False) | Captures all browser console messages (logs, warnings, errors) during the crawl. Available in `result.console_messages`. |
+```
+
+These changes demonstrate how to use the new network and console capturing features in the CrawlerRunConfig.
