feat(Port80Handler): Add glob pattern support for domain certificate management in Port80Handler. Wildcard domains are now detected and skipped in certificate issuance and retrieval, ensuring that only explicit domains receive ACME certificates and improving route matching.

+## 2025-03-18 - 4.3.0 - feat(Port80Handler)
+Add glob pattern support for domain certificate management in Port80Handler. Wildcard domains are now detected and skipped in certificate issuance and retrieval, ensuring that only explicit domains receive ACME certificates and improving route matching.
+
+- Introduced isGlobPattern to detect wildcard domains.
+- Added getDomainInfoForRequest and domainMatchesPattern methods to enable glob pattern matching for domain configurations.
+- Modified setCertificate and getCertificate to prevent certificate operations for glob patterns.
+- Updated request handling to skip ACME challenge processing and certificate issuance for wildcard domains.
+- Updated documentation and tests to reflect the new glob pattern support.
+
 ## 2025-03-18 - 4.2.6 - fix(Port80Handler)
 Restrict ACME HTTP-01 challenge handling to domains with acmeMaintenance or acmeForward enabled
