test: run migration CLIs in an in-cluster Job

[tmshort]

Summary

Adds an E2E scenario that runs the migration command-line tools inside a Kubernetes Job rather than from the test host.

The test builds a migration-tool image, runs the catalog and operator migration commands in the fixture Kind cluster, and keeps the Job for log inspection. It exercises in-cluster authentication and catalog endpoint access while retaining the existing host-run fixture coverage.

Also updates the migration test workflow and local E2E instructions for the in-cluster Job target.

Validation

Compiled the E2E package with: go test -count=1 -tags=e2e ./test/e2e/migration

Summary by CodeRabbit

• New Features

  • Migration commands can now run from within a Kubernetes cluster using projected service-account credentials when no kubeconfig is provided.
  • Added support for running catalog and operator migrations as an in-cluster Job.

• Bug Fixes

  • Explicit kubeconfig settings and the KUBECONFIG environment variable continue to take precedence, preserving configuration errors when applicable.

• Tests

  • Added end-to-end coverage for in-cluster migration Jobs, including completion and migration-result validation.

📝 Walkthrough

Walkthrough

The migration tools now support projected ServiceAccount credentials. New targets build and load an uninstrumented image, run migration from a Kubernetes Job, validate results, and execute the suite in CI.

Changes

In-cluster migration E2E

Layer / File(s)	Summary
In-cluster client authentication migration/examples/cmd/migrate-catalogs-v0-to-v1/*, migration/examples/cmd/migrate-operators-v0-to-v1/*	Both CLIs use rest.InClusterConfig() when no explicit kubeconfig is set. Tests cover the kubeconfig selection rule.
Migration Job execution .bingo/*, migration.mk, test/e2e/migration/*	The Make targets build and load an uninstrumented migration image. The E2E test creates a ServiceAccount, elevated binding, and Kubernetes Job, then validates migration completion and cleanup conditions.
CI and test strategy wiring .github/workflows/migration-test.yaml, specs/20260821-migration-v0-to-v1/e2e.md	CI runs the new suite and always tears down the fixture cluster. The strategy document defines the suite, run order, required gate status, and Kind version update.

Merge Risk: 🔵 Low · up to 13f09

A prior interrupted test run can make the next in-cluster migration check wait until CI times out. Bound the namespace deletion before merging.
