minio: revert to single-node after measuring the real cost of sharding
The 4-node/8-drive erasure-coded cluster matched HAL's topology faithfully, but real throughput testing against both showed why that costs more than it's worth here: every write on the sharded cluster fans out across 4 processes over the internal network with erasure-coding overhead, capping safe throughput around 1.3-2 MiB/s and breaking outright above ~256 concurrent transfers (IncompleteBody errors, confirmed via a controlled 512x test). The identical copy against a single-node instance sustained 23+ MiB/s at the same concurrency with zero errors — over 10x faster, verified side-by-side, not assumed. Trades away erasure-coded redundancy (no single-drive fault tolerance) for that throughput. Deliberate, and reversible if it turns out to matter later -- the data itself is migrated over the S3 API either way, so the storage topology underneath isn't locked in by anything upstream of it.
