Create 11 sg-evals mirrors for scaling-gap repos

Mid-tier (500MB-1GB): grpc, tidb, ceph, beam, bazel
XL (>1.5GB): elasticsearch, godot, roslyn, TypeScript, cockroach, ClickHouse

Fixed fixture revisions: roslyn v4.12.0→NET-SDK-9.0.100 (actual tag),
ClickHouse v24.12→v24.12.1.1614-stable (actual tag). Mirror names
unchanged since they're referenced in generated Dockerfiles.

All mirrors created via scripts/create_sg_mirrors.py and verified
accessible on GitHub. Still need Sourcegraph indexing.
