Fix IBM ppc64le/s390x minikube setup for reliable e2e tests
- Increase download timeout from 180s to 600s for large binaries on slow IBM networks - Fix rootful mode: unset MINIKUBE_ROOTLESS env var and use --rootless=false flag - Update kicbase to v0.0.48 to match minikube v1.37.0 - Use bridge CNI for ppc64le/s390x (kindnet lacks ppc64le images) - Add safe cleanup for shared CI machines (only kills orphaned processes) - Configure root-level podman for minikube rootful mode - Test podman functionality before proceeding 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
