feat(profiles): add CLI command for crawling with browser profiles

Adds new functionality to crawl websites using saved browser profiles directly from the CLI.
This includes:
- New CLI option to use profiles for crawling
- Helper functions for profile-based crawling
- Fixed type hints for config parameters
- Updated example to show browser window by default

This makes it easier for users to leverage saved browser profiles for crawling without writing code.
