/**
 * 05 – Sync verification and cleanup.
 *
 * Exercises the dynamic aspects of the sync pipeline:
 *   • Adding a repo to the fake GitHub at runtime and verifying the app
 *     discovers it on the next sync
 *   • Deep content-integrity checks on repos mirrored during earlier suites
 *   • Resetting the fake GitHub store to its defaults
 *
 * Prerequisites: 02-mirror-workflow.spec.ts must have run so that repos
 * already exist in Gitea.
