🌟 Release Highlights — v0.3.30

This maintenance release sharpens domain validation for Kubernetes and other topology-aware deployments, alongside internal code quality improvements.

🐛 Bug Fixes & Improvements

• RFC-1123 topology hostnames now accepted — gateway.domain validation has been widened to accept RFC-1123 topology hostnames (e.g., my-service.namespace.svc.cluster.local), fixing a common issue for users deploying MCP Gateway in Kubernetes environments. (#8044)

🔧 Internal

• Eliminated duplicate cursor cycle detection in MCP pagination by consolidating logic into a single PaginateAll helper (#8049)
• Extracted SortedSetKeys and atomicWriteFile utilities to reduce code duplication (#8042)
• Extracted first_matching_label helper in Rust guard and expanded label-check unit test coverage (#8047)
• Improved test coverage for the urlutil package (#8008)
