These issues and fixes address a Windows-specific problem where the update pipeline stalls or deadlocks because gateway child processes (MCP/perfmon helpers) remain alive inside the venv, preventing the venv guard from clearing. Fixes focus on reaping or killing those venv-resident children before proceeding with updates or venv recreation.
