Under ASAN+mbedTLS, the default 4-way sharding loads CI runners enough
that timing-sensitive ServerTest cases (Delete, PostMethod2, GetStreamed,
...) flake on what looks like first-request keep-alive reuse. Reducing
to 2 shards halves contention and historically stabilizes these on local
runs. The total test time goes up roughly 1.5x (still well under the job
budget) which is an acceptable trade for reliability.
