Launch: On-call rotation + incident runbook

[psdjungpulzze]

Before going live:

• Set up on-call schedule (PagerDuty / Opsgenie / plain phone rotation)
• Define SEV1/SEV2/SEV3 severity levels and response SLAs
• Write incident runbook: how to roll back a bad deploy, restart worker, flush Redis queue
• Add runbook link to status page and internal wiki
• Test an alert end-to-end (fire a fake alert, confirm the right person is paged)
