OpenShift pull-through cache on a bastion (vSphere IPI, 4.20)

Reduce cloud-provider egress for scale-out perf testing: every node image pull is rewritten to a registry:2 pull-through cache running on the bastion host. First pull of a unique image still goes upstream (bastion → provider); all subsequent pulls from any node are served from the bastion at L2 speed.

Tested on OpenShift 4.20 / vSphere IPI, CRI-O 1.36.5, ~50-80 churning autoscaled workers pulling quay-proxy.ci.openshift.org CI images.

This is a user-global setup (~/.cursor/). It applies to every project you open in Cursor.

Prerequisites

1. Install Serena (do not use marketplace/plugin installers):

Pangolin 1.18 upgrade: SqliteError: no such column: resources.health

A troubleshooting guide for Pangolin upgrades from 1.17.x → 1.18.x when the SQLite database schema is out of sync with the running application.

Tested fix path: seed versionMigrations with 1.17.0, then re-run migrations.
