agents-dev notifications: operator runs Prism (phoebe-lab/prism) — ntfy-compatible gateway at https://prism.bigb.es/{topic}, bearer key PRISM_API_KEY in the stack .env, delivers to Telegram and owns TG proxy egress itself (patched Telego + lab singbox SOCKS5). agents-dev publishes to it via internal/ntfy (plain lab-local HTTPS, inside NO_PROXY) — the direct internal/telegram path and VM-local-singbox concern are no longer needed for the daemon.
