Pull Request Overview

This PR optimizes domain lookup performance by replacing a slice-based domain storage with a map-based approach for faster O(1) lookups instead of O(n) iterations. It also adds support for loading domains from files.

• Changed domain storage from []string to map[string]struct{} for faster lookup performance
• Added file support to load domains from external files via new DomainsCrawlFile configuration option
• Updated the AddElements function signature to accept both inline domains and file paths
