pm2-self-heal: migrate alerts from Zulip to Telegram

- abiba-zulip PM2 process decommissioned (2026-07-04)
- Replace Zulip stream alerts (agent-hub > alerts-pm2) with Telegram DM
- Remove stale abiba-zulip monitoring block (process no longer exists)
- Retain abiba-telegram auto-restart (critical — sole communication bridge)
- Token sourced from extension .env, not hardcoded
