Add MCP release QA skill 🤖🤖🤖

[JasonColapietro]

Summary

• Add an mcp-release-qa skill for release-time MCP protocol verification.
• Generate the corresponding skills index entry.

Why

The existing MCP skills cover configuration security, implementation security,
server generation, and CLI usage. This adds a focused release workflow for
checking a real protocol session, runtime/source/documentation parity, failure
paths, published contracts, and install behavior.

Testing

• npm ci
• npm run skill:validate
• npm run build
• git diff --check
• Confirmed the generated skills index includes mcp-release-qa.

Scope

• One new self-contained skill.
• One generated documentation entry.
• No runtime code or existing skill behavior changes.
