Adds opt-in extension package internal/automc/ that: - Subscribes to Postgres notifications on a 'servers' table and pushes route changes into server.Routes (no file I/O, no fsnotify). - Provides a WakerFunc that POSTs to a configurable HTTP control plane (server-manager) and polls until state=running. When AUTOMC_DSN is unset, Wire() is a no-op and the binary behaves exactly like upstream itzg/mc-router. Single patch site in main.go (import + 4-line call) keeps upstream rebases trivial. See docs/AUTOMC.md for env vars and the expected DB schema/trigger.
