/**
 * Hostname / domain matching utilities for license validation.
 *
 * Supports:
 *  - Exact domain match (example.com)
 *  - Wildcard domains (*.example.com)
 *  - Universal wildcard (*)
 *  - IPv4 exact match
 *  - IPv4 wildcard patterns (e.g. 10.*, 192.168.*.*)
 *  - IPv4 CIDR ranges (e.g. 192.168.2.0/24)
 *
 * This module is intentionally isolated from the license validation flow
 * to reduce complexity, minimize regression risks, and simplify future
 * extensions (e.g. IPv6 support).
