This release enhances operational efficiency with zero-downtime reloading for both firewall rules and TLS certificates. Monitoring capabilities are significantly improved with more granular error metrics for precise alerting. System performance under load is increased through proactive rate limiting and request handling optimizations.

### Improvements
*   Apply firewall rule updates dynamically with zero downtime using a `SIGHUP` signal to improve service availability and operational agility. (#90)
*   Reload TLS certificates automatically without a service restart for seamless certificate rotation and simplified security maintenance. (#91)
*   Enable granular monitoring and alerting with a new `status_code` label on the `minwall_errors_total` Prometheus metric. (#96)
*   Improve system responsiveness under high load by proactively rejecting requests that would exceed the configured wait time, providing immediate client feedback. (#94)
*   Optimize TCP network settings on Linux to increase data transfer throughput and improve the handling of idle or unresponsive network connections. (#89)
*   Reduce CPU consumption during high traffic by optimizing the parsing of URL query parameters and hostnames. (#97)
*   Standardize license handling with clearer status feedback, grace period warnings, and a new `--license` flag for flexible configuration. (#100, #101)
*   Reduce log noise by suppressing low-level web server messages, allowing operators to focus on critical application events. (#93)

### Bug Fixes
*   Return the correct `408 Request Timeout` HTTP status code for rate-limited requests, enabling more precise client-side error handling. (#95)
*   Prevent a potential application crash during startup on systems with specific network interface configurations. (#98)
*   Ensure server startup logs accurately distinguish between HTTP and HTTPS services and reduce non-critical errors during shutdown. (#99)

### Security Updates
*   Harden the software supply chain by adding cryptographic verification to the official Docker image build process, ensuring binary integrity. (#87)
