E137 - Claude Code Fixes Silent MCP Failures in 2.1.28.1

We dig into a frustrating Claude Code bug where MCP tools can silently disappear, then break down how release 2.1.28.1 improves validation by catching dropped .mcp.json entries, undeclared template variables, and insecure HTTP endpoints before they hit production.

We also cover a stricter schema gotcha for existing CI pipelines and a handy quality-of-life update for disabling automated Git commit and PR attribution footers.
