What
When Claude Code handles Ctrl-C (SIGINT) to shut down MCP servers, the cleanup code used a guard flag to prevent the cleanup from running twice. Due to a bug, it checked one variable but set a different, unrelated one, so the guard never actually took effect. It now correctly sets the same flag it checks.
Why
This fixes a bug that could have allowed MCP server cleanup on Ctrl-C to run more than once instead of being properly guarded against double execution.
