When GitHub Actions Goes Silent: The Pending-Forever Bug I Hit Shipping My MCP Server to npm

I have an open-source MCP server. I tag a release, push, GitHub Actions builds, npm publishes, MCP Registry updates. That's the contract. It worked for v2.7.6 through v2.8.4. Then v2.8.5 didn't publish. Neither did v2.8.6. Or v2.9.0. Or v2.9.1. Or v2.9.2. Or v2.9.3. Six releases stuck. Not failing —
