feat(cli): add browser profile management functionality

Adds new interactive browser profile management system that allows users to:
- Create and manage browser profiles for authenticated crawling
- List existing profiles with detailed information
- Delete unused profiles
- Use profiles during crawling with the new -p/--profile flag

Also restructures CLI to use Click groups and adds humanize dependency for better size formatting.
