feat(routing): Implement unified routing and matching system

- Introduced a centralized routing module with comprehensive matchers for domains, headers, IPs, and paths.
- Added DomainMatcher for domain pattern matching with support for wildcards and specificity calculation.
- Implemented HeaderMatcher for HTTP header matching, including exact matches and pattern support.
- Developed IpMatcher for IP address matching, supporting CIDR notation, ranges, and wildcards.
- Created PathMatcher for path matching with parameter extraction and wildcard support.
- Established RouteSpecificity class to calculate and compare route specificity scores.
- Enhanced HttpRouter to utilize the new matching system, supporting both modern and legacy route configurations.
- Added detailed logging and error handling for routing operations.
