—Added "fluxproof_get_free_key" (5 tools before, 6 now)
Create a free FluxProof API key: one page, checked daily, for 30 days, no card. One per network per month. Use after a successful preflight when the user wants the page watched, then pass the key to fluxproof_create_monitor. The key is shown once: give it to the user and treat it as a secret.
