* Tests for Host lookup algorithm

* that supports exact matches, single wildcards (*), and double wildcards (**).

* Pattern matching priority (highest to lowest):
* 1. Exact match (example.com)
* 2. Single wildcard (*.example.com matches any.example.com)
* 3. Double wildcard (**.example.com matches any.sub.domain.example.com)
*
* These tests validate the lookup algorithm without requiring a Redis connection.
