A one-flag kill-switch: when set, the pack installs no middleware, registers no
refresh routes, computes no fingerprint and exposes no graph node — ComfyUI runs
exactly as if it weren't installed. Only the read-only /tenaciousload/status
route stays so the loading-screen overlay still shows (a generic 'Loading node
definitions…' bar, since there's no build to track). The refresh menu buttons
hide themselves when status reports enabled:false.
Useful for A/B testing or as a safety kill-switch. Requires a restart (the
middleware is installed at startup). Unit-tested both modes.
