alexei.dolgolyov bbcc4f55f0 feat(docker-watcher): phase 7 - deployer & health checker
Deploy orchestrator with full pipeline: pull → create container →
start → network → NPM proxy → health check. Rollback on failure,
multi-instance support, max_instances enforcement, webhook notifications.
Fix NPM auth in rollback and error logging in removeInstance.
