On Windows, PIDs get reused after reboot. The daemon state check previously only verified if a PID was alive via process.kill(pid, 0), which could return true for a completely unrelated process that was assigned the same PID after a system restart. This adds an HTTP health check to the daemon's control server after the PID alive check. If the PID is alive but the HTTP ping fails, the stale state is cleaned up, allowing a fresh daemon to start.
