Cardano Updates

Rename `sequential-engine: true/false` to `engine: sequential | actor` with
actor as the default to avoid surprises. Add parameters/turbo.yaml convenience
preset (sequential engine, 6 shards, zero-latency-clusters) for ~5x speedup.
Update CLAUDE.md and README.md with engine and shard documentation.

Currently, the `B` constructor contains a `ByteString` (pinned in
memory) with a max length of 64 bytes. Since the `ByteString` is small
and can be instantiated frequently, it makes more sense to use an
unpinned byte array representation (`Data.Array.Byte.ByteArray`) so
that we can take advantage of Haskell's garbage collection to improve
memory allocation of objects in the heap.

We also place an upper bound on `nothunks` because of new orphan
instance (`instance NoThunks ByteArray`) that is going to be upstreamed.
